Test opendev watcher master content in CI job

In order to test opendev watcher master content in CI job, this pr
adds following thigs:
* opendev-master-watcher-operator-pipeline project template which
  will run meta content provider from master and then Deploy EDPM
  job watcher-operator-validation-master from mastter content.

* It changes the existing job watcher-operator-validation (still
  deploying the antelope content) with update_containers: false to avoid
  using meta content provider containers.

* It also updates the existing watcher-operator-validation and watcher-operator-kuttl
  job to use openstack-meta-content-provider-master as a job
  dependencies.

Depends-On: https://review.opendev.org/c/openstack/watcher/+/938893
