Find alternate way and replace "openshift-dev.pem" SSH key from wmco CI/CD and other places

Description

 openshift-dev.pem private SSH key from the openshift/shared-secrets repository is going to be removed this week, and references to it in our internal documentation will also be removed.  As winc team use this key to share access to build and test instances, we need to develop a new process to do so. A promising option is BitWarden, which allows one to share keys and other sensitive artifacts securely between teammates.

If CI processes inject the openshift-dev.pem private key or a matching public key into our build instances, we need to follow the OpenShift CI documentation for adding secrets to replace it.

Engineering Details

The hack/e2e script can generate a key to be used when creating Windows nodes.
 

Acceptance Criteria

• CI/CD pipeline should work without any regression.

• Should be able to create clusters in AWS/AZURE/vSphere/GCP/Nutanix with new solution. 

• Openshift-dev.pub public key is removed from vSphere golden images and updated with the new key.
