Added Github workflow for running e2e tests

[harishsurf]

Description of the change:
Added a workflow yml file that triggers a Github Action which runs our e2e-tests using kind cluster for every PR created against this repo.
This PR also adds ginkgo's Skip() as a workaround for a failing spec in catalog_e2e. See #1380 for more details

Motivation for the change:

Reviewer Checklist

• Implementation matches the proposed design, or proposal is updated to match implementation
• Sufficient unit test coverage
• Sufficient end-to-end test coverage
• Docs updated or added to /docs
• Commit messages sensible and descriptive

Thanks for setting this up! I just have a few nits -- we should be able to flip this on soon.

error copying old registry file: failed to exec []string{"skopeo", "--debug", "--insecure-policy=true", "copy", "--dest-tls-verify=false", "--format=v2s2", "--dest-no-creds=true", "docker://quay.io/olmtest/catsrc-update-test:old", "docker://localhost:5000/catsrc-update:xt2t79"}: exec: "skopeo": executable file not found in $PATH

looks like we need to install skopeo in the test vm

IIRC there is a bit more work required than that. We're tracking it here: #1380 -- I've asked Harish to temporarily mark it as skipped when it runs as part of this job so that we can get some utility from this right away.
