[COMMON] Handle TLS/Non-TLS for Service

Current service and headlessService templates doesn't handle the fact
that out of cluster ports must be TLS encrypted only.
With a new (backward compatible) DSL, this is now possible.

In values.yaml, all ports in service part with port AND plain_port will
have the ability to be HTTP or HTTPS depending on the context.

Per default, they'll be HTTPS.

TLS choice will be done according this table:

| tlsOverride | global.tlsEnabled | global.serviceMesh.enabled | global.serviceMesh.tls | result |
|-------------|-------------------|----------------------------|------------------------|--------|
| not present | not present       | not present                | any                    | true   |
| not present | not present       | false                      | any                    | true   |
| not present | not present       | true                       | false                  | true   |
| not present | not present       | true                       | true                   | false  |
| not present | true              | any                        | any                    | true   |
| not present | false             | any                        | any                    | false  |
| true        | any               | any                        | any                    | true   |
| false       | any               | any                        | any                    | false  |

Service template will create one or two service templates according to this table:

| serviceType   | both_tls_and_plain | result       |
|---------------|--------------------|--------------|
| ClusterIP     | any                | one Service  |
| Not ClusterIP | not present        | one Service  |
| Not ClusterIP | false              | one Service  |
| Not ClusterIP | true               | two Services |

If two services are created, one is ClusterIP with both crypted and plain
ports and the other one is NodePort (or LoadBalancer) with crypted port only.

+Current given templating functions
+==================================
+
+
+In order to have a consistent deployments of ONAP components, several templating
+functions are proposed in  `kubernets/common/common/templates` folder.
+This file list them and gives examples for the most used.
+All these templating functions have a description in their own file, here we
+only give an overview.

+The most widely use templates is the last (`common.secret`).
+It should be the only (except license part) line of your secret file:
+
+.. code-block:: yaml
+
+  {{ include "common.secret" . }}
+
+In order to have the right values set, you need to create the right
+configuration in `values.yaml` (example taken from mariadb configuration):
+
+.. code-block:: yaml
+
+  secrets:
+  - uid: 'db-root-password'
+    type: password
+    externalSecret: '{{ tpl (default "" .Values.config.db.rootPasswordExternalSecret) . }}'

+.. code-block:: yaml
+
+  ingress:
+    enabled: false
+    service:
+      - baseaddr: "clamp"
+        name: "clamp"
+        port: 443
+    config:
+      ssl: "redirect"
+
+Labels
+------

+      spec:
+      {{- if .Values.nodeSelector }}
+        nodeSelector:
+  {{ toYaml .Values.nodeSelector | indent 8 }}
+      {{- end }}
+        volumes:
+        {{- if .Values.externalConfig }}
+          - name: config
+            configMap:
+              name: {{ include "common.fullname" . }}-external-config
+        {{- end}}
+        ...
+        containers:
+        - name: {{ include "common.name" . }}
+          image: "{{ include "common.repository" . }}/{{ .Values.image }}"
+        ...
+
+Namespace
+---------
+
+These functions are defined in
+`kubernetes/common/common/templates/_namespace.tpl`.
+
+The goal of these functions is to always retrieve the namespace the same way.
+
+* `common.namespace`: Generate the namespace for a chart. Shouldn't be used
+  directly but use `common.resourceMetadata` (which uses it).
+
+
+Repository
+----------
+
+These functions are defined in
+`kubernetes/common/common/templates/_repository.tpl`.
+
+The goal of these functions is to generate image name the same way.
+
+* `common.repository`: Resolve the name of the common image repository.
+* `common.repository.secret`: Resolve the image repository secret token.
+
+
+Resources
+---------
+
+These functions are defined in
+`kubernetes/common/common/templates/_resources.tpl`.
+
+The goal of these functions is to generate resources for pods the same way.
+
+* `common.flavor`: Resolve the name of the common resource limit/request flavor.
+  Shouldn't be used alone.
+* `common.resources`: Resolve the resource limit/request flavor using the
+  desired flavor value.
+
+
+Storage
+-------
+
+These functions are defined in
+`kubernetes/common/common/templates/_storage.tpl`.
+
+The goal of these functions is to generate storage part of Deployment /
+Statefulset and storage resource (PV, PVC, ...) in a consistent way.
+
+* `common.storageClass`: Expand the name of the storage class.
+* `common.needPV`: Calculate if we need a PV. If a storageClass is provided,
+  then we don't need.
+* `common.replicaPV`: Generate N PV for a statefulset
+
+
+Pod
+---
+
+These functions are defined in `kubernetes/common/common/templates/_pod.tpl`.
+
+* `common.containerPorts`: generate the port list for containers. See Service
+  part to know how to declare the port list.
+
+Here's an example of use of these functions in a Deployment template (example
+taken on nbi):
+
+.. code-block:: yaml
+
+  apiVersion: apps/v1
+  kind: Deployment
+  ...
+  spec:
+    ...
+    template:
+      ...
+      spec:
+        containers:
+        - name:  {{ include "common.name" . }}

+
+
+Service
+-------
+
+These functions are defined in
+`kubernetes/common/common/templates/_service.tpl`.
+
+The goal of these functions is to generate services in a consistent way.
+
+* `common.servicename`: Expand the service name for a chart.
+* `common.serviceMetadata`: Define the metadata of Service. Shouldn't be used
+  directly but used through `common.service` or `common.headlessService`.
+* `common.servicePorts`: Define the ports of Service. Shouldn't be used directly
+  but used through `common.service` or `common.headlessService`.
+* `common.genericService`: Template for creating any Service. Shouldn't be used
+  directly but used through `common.service` or `common.headlessService`. May be
+  used if you want to create a Service with some specificities (on the ports for
+  example).
+* `common.needTLS`: Calculate if we need to use TLS ports on services
+* `common.service`: Create service template.
+* `common.headlessService`: Create headless service template
+
+
+The most widely used templates are the two last (`common.service` and
+`common.headlessService`).
+It should use with only one (except license part) line of your service (or
+service-headless) file:
+
+.. code-block:: yaml
+
+  {{ include "common.service" . }}
+
+In order to have the right values set, you need to create the right
+configuration in `values.yaml` (example taken from nbi configuration + other
+part):
+
+.. code-block:: yaml
+
+  service:
+    type: NodePort
+    name: nbi
+    annotations:
+      my: super-annotation
+    ports:
+      - name: api
+        port: 8443
+        plain_port: 8080
+        port_protocol: http
+        nodePort: 74
+      - name: tcp-raw
+        port: 8459
+        nodePort: 89
+
+
+would generate:
+
+.. code-block:: yaml
+
+  apiVersion: v1
+  kind: Service
+  metadata:
+    annotations:

+ServiceMesh
+-----------
+
+These functions are defined in
+`kubernetes/common/common/templates/_serviceMesh.tpl`.
+
+The goal of these functions is to handle onboarding of ONAP on service mesh.
+
+* `common.onServiceMesh`: Calculate if we if we are on service mesh
+
+
+
+MariaDB
+-------
+
+These functions are defined in
+`kubernetes/common/common/templates/_mariadb.tpl`.
+
+The goal of these functions is to simplify use of mariadb and its different
+values.
+
+* `common.mariadb.secret.rootPassUID`: UID of mariadb root password
+* `common.mariadb.secret.rootPassSecretName`: Name of mariadb root password
+  secret
+* `common.mariadb.secret.userCredentialsUID`: UID of mariadb user credentials
+* `common.mariadb.secret.userCredentialsSecretName`: Name of mariadb user
+  credentials secret
+* `common.mariadbService`: Choose the name of the mariadb service to use
+* `common.mariadbPort`: Choose the value of mariadb port to use
+* `common.mariadbSecret`: Choose the value of secret to retrieve user value
+* `common.mariadbSecretParam`: Choose the value of secret param to retrieve user
+  value
+
+PostgreSQL
+----------
+
+These functions are defined in
+`kubernetes/common/common/templates/_postgres.tpl`.
+
+The goal of these functions is to simplify use of postgres and its different
+values.
+
+* `common.postgres.secret.rootPassUID`: UID of postgres root password
+* `common.postgres.secret.rootPassSecretName`: Name of postgres root password
+  secret
+* `common.postgres.secret.userCredentialsUID`: UID of postgres user credentials
+* `common.postgres.secret.userCredentialsSecretName`: Name of postgres user

+* `common.postgres.secret.primaryPasswordSecretName`: Name of postgres primary
+  credentials secret
+
+
+Utilities
+---------
+
+These functions are defined in
+`kubernetes/common/common/templates/_tplValue.tpl`.
+
+The goal of these functions is provide utility function, usually used in other
+templating functions.
+
+* `common.tplValue`: Renders a value that contains template.
