Make target e2e in operator repo: https://github.com/openshift/cert-manager-operator/ currently runs all test cases assuming we run the tests on OpenShift on AWS infra. The same is run on pre-submits in the CI, as the cluster created in CI e2e test run is also only AWS. It is desirable to make test cases for GCP, Azure, IBM Cloud, etc. be part of the same Ginkgo suite we have but have labels to differentiate.

Acceptance criteria: run tests such that running e2e make target we can specify the cloud provider and ginkgo filters accordingly viz. internal implementation can use labels or env vars.
