AssertEncryptionConfig checks if the encryption config holds only targetGRs, this ensures that only those resources were encrypted, we don't check the keys because e2e tests are run randomly and we would have to consider all encryption secrets to get the right order of the keys.

TestEncryptionRotation first encrypts data with aescbc key then it forces a key rotation by setting the "encyrption.Reason" in the operator's configuration file.

E is like testing.T except it overloads some methods to print to stdout when the encryption tests are run from a local machine.
