As a developer, I want BYOH instances to be updated when the private key secret changes so that SSH connections remain possible, regardless of the current cloud private key.

Description

Currently BYOH doesn't have the functionality of rotating keys on the VMs. This means that, when the private key secret is changed (as we do in our e2e tests), we are no longer able to SSH into BYOH instances that were created with the previous key.

Therefore, we are forced to re-create the valid key secret (which kicks off time-consuming reconciling) before we can proceed with tests, e.g. deconfigure tests since we need to SSH into BYOH instances to deconfigure. We should remove the need to recreate the same key that was present at the time of BYOH node creation.

Acceptance Criteria

• When the private key secret changes, BYOH instances are updated to allow SSH connections with the new key.
• Remove all comments/TODOs in e2e tests that reference this story https://issues.redhat.com/browse/WINC-655
