Validate config before using it

[nirs]

Before using the config we need to validate it with the clusters.

What to validate

• clusters are accessible
• drpolicy exists and valid
• drclusters exists and valid
• clusters names match drpolicy drclusters
• ramen deployment is healthy
• storage classes exists
• other?

This should be implemented in e2e since we need it also for e2e.

Report

Collect resources as we inspect them:

report/
  test-run.log
  validate/
    hub/
      dr-policy.yaml

Maybe use gather directory layout?

report/
  validate/
    hub/
      cluster/
        group/
          kind/
            dr-policy.yaml
