e2e: tests should not rely on ocm-ramen-samples

[raghavendra-talur]

It would be really useful to have a set of e2e tests where the workload is defined and generated within the e2e code and used on the fly.

What we would need is a git repo to host the temporary artifacts. I think it should be easy to host a git service in the hub cluster and then use it for ACM/OCM.

Another way may be to use s3 store as the backend instead of git. We already have minio on drenv and whatever s3 solution openshift is using. We just need to push the resources there and configure the channel, subscription, and applicationset to use it.

This will allow us to create workloads with many flavors(pvc types, numbers).
