Task

In order to use skopeo with and existing openshift pullsecret for fetching the index and plugin containers from reg.rh.io, we need two things:

• a modified registries.conf file where the internal registry for the cluster is used instead of reg.rh.io, along with the ImageStreams created in RHIDP-11487
• a modified invocation to skopeo in https://github.com/redhat-developer/rhdh/blob/main/docker/test_install-dynamic-plugins.py to do a skopeo login, then use an auth.json file that includes the cluster's pullsecret for reg.rh.io

NOTES:

• Make it possible to override the url to the internal OCP registry: env var in the install-dynmaic-plugins.py script
• Need to consider edge cases:
  • if there is no internal registry available
