  This template generates a Kubernetes init containers common template to enable applications to provision
  DMaaP feeds (on Data Router), with associated authorization.
  DMaap Bus Controller endpoints are used to provision:

  - Feed on DR, with associated user authentication.

  common.dmaap.provisioning.initContainer:
  This template make use of Dmaap Bus Controller docker image to create resources on Dmaap Data Router
  microservice, with the help of dbc-client.sh script it makes use of Bus Controller API to create Feeds.
  If the resource creation is successful via script response is logged back at particular location with
  appropriate naming convention.

  More details can be found at :
  (https://wiki.onap.org/pages/viewpage.action?pageId=103417564)

  The template directly references data in .Values, and indirectly (through its
  use of templates from the ONAP "common" collection) references data in .Release.

  Parameter for _dmaapProvisioning to be defined in values.yaml
