[DCAEGEN2] Deploy DCAE microservices via Helm
Deploy DCAE microservices using Helm instead of having the DCAE bootstrap container deploy them using Cloudify. Charts for the microservices are found under oom/kubernetes/dcaegen2-services.

+dcaegen2-services-common.microserviceDeployment:
+This template produces a Kubernetes Deployment for a DCAE microservice.
+
+All DCAE microservices currently use very similar Deployments. Having a
+common template eliminates a lot of repetition in the individual charts
+for each microservice.
+
+The template expects the full chart context as input. A chart for a
+DCAE microservice references this template using:
+{{ include "dcaegen2-services-common.microserviceDeployment" . }}
+The template directly references data in .Values, and indirectly (through its
+use of templates from the ONAP "common" collection) references data in
+.Release.
+
+The exact content of the Deployment generated from this template
+depends on the content of .Values.
+
+The Deployment always includes a single Pod, with a container that uses
+the DCAE microservice image.
+
+The Deployment Pod may also include a logging sidecar container.
+The sidecar is included if .Values.logDirectory is set. The
+logging sidecar and the DCAE microservice container share a
+volume where the microservice logs are written.
+
+The Deployment includes an initContainer that pushes the
+microservice's initial configuration (from .Values.applicationConfig)
+into Consul. All DCAE microservices retrieve their initial
+configurations by making an API call to a DCAE platform component called
+the config-binding-service. The config-binding-service currently
+retrieves configuration information from Consul.
+
+The Deployment also includes an initContainer that checks for the
+readiness of other components that the microservice relies on.
+This container is generated by the "common.readinessCheck.waitfor"
+template.
+
+If the microservice acts as a TLS client or server, the Deployment will
+include an initContainer that retrieves certificate information from
+the AAF certificate manager. The information is mounted at the
+mount point specified in .Values.certDirectory. If the microservice is
+a TLS server (indicated by setting .Values.tlsServer to true), the
+certificate information will include a server cert and key, in various
+formats. It will also include the AAF CA cert. If the microservice is
+a TLS client only (indicated by setting .Values.tlsServer to false), the
+certificate information includes only the AAF CA cert.
