metering labels

[eguzki]

https://issues.redhat.com/browse/THREESCALE-7751

• Added metering labels to operator deployment

• Added metering labels to apicast pod (via deployment pod template labels)

  apiVersion: v1
  kind: Pod
  metadata:
  labels:
  com.company: Red_Hat
  deployment: apicast-apicast1
  pod-template-hash: 55f85485ff
  rht.comp: 3scale_apicast
  rht.comp_ver: master
  rht.prod_name: Red_Hat_Integration
  rht.prod_ver: master
  rht.subcomp: apicast
  rht.subcomp_t: application

• Added test-manifest-version circleci check to verify operator labels match operator version

• Added version.ThreescaleRelease attribute to be used in the metering labels

• Added reconcilliation of deployment pod template labels. Merge type (missing will be added, existing updated)

• No need to add upgrade, as previous releases did not have metering labels. However, it will be needed for future releases as the release number is included in the metering labels

Metering operator has been deprecated. From https://docs.openshift.com/container-platform/4.8/release_notes/ocp-4-8-release-notes.html#ocp-4-8-metering

Does not make sense to implement integration with a deprecated feature

Reopening due to this comment https://issues.redhat.com/browse/THREESCALE-5313?focusedCommentId=19054318&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-19054318

It seems that metering labels will be read by a new operator with more limited scope but it will use the same label schema
