"16-02-2022: Prevent clone of multi-node VDB"

[pioro]

Is your feature request related to a problem? Please describe.
Multi-node VDB can't be cloned by Delphix and there is no check to stop it in the plugin.
Provisioning of the clone VDB will start but it will be never finished and job will be running until 3600 sec timeout.
After that a clean up of target server is required.

Describe the solution you'd like
Add a check to the plugin to raise an error when user is trying to clone multi-node VDB
before starting any provisioning activities
