Finally switch both CI and ART to the refactored aws-ebs-csi-driver-operator.

The functionality and behavior should be the same as the existing operator, however, the code is completely new. There could be some rough edges. See https://github.com/openshift/enhancements/blob/master/enhancements/storage/csi-driver-operator-merge.md 

Ci should catch the most obvious errors, however, we need to test features that we do not have in CI. Like:

• custom CA bundles
• cluster-wide proxy
• custom encryption keys used in install-config.yaml
• government cluster
• STS
• SNO
• and other
