In order to use certServiceClient it is needed do define certificates array in target component values.yaml. Each
certificate will be requested from separate init container

Minimum example of array in target component values.yaml:
certificates:
  - mountPath:  /var/custom-certs
    commonName: common-name

Full example (other fields are ignored):
certificates:
  - mountPath:  /var/custom-certs
    caName: RA
    keystore:
      outputType:
        - jks
    commonName: common-name
    dnsNames:
      - dns-name-1
      - dns-name-2
    ipAddresses:
      - 192.168.0.1
      - 192.168.0.2
    emailAddresses:
      - email-1@onap.org
      - email-2@onap.org
    uris:
      - http://uri-1.onap.org
      - http://uri-2.onap.org
    subject:
      organization: Linux-Foundation
      country: US
      locality: San Francisco
      province: California
      organizationalUnit: ONAP

There also need to be some includes used in a target component deployment (indent values may need to be adjusted):
  1. In initContainers section:
    {{ include "common.certServiceClient.initContainer" . | indent 6 }}
  2. In volumeMounts section of container using certificates:
    {{ include "common.certServiceClient.volumeMounts" . | indent 10 }}
  3. In volumes section:
    {{ include "common.certServiceClient.volumes" . | indent 8 }}
