Cleanup VMs renamed to Deprecated_* after AppFlows failover event

[oktain89]

What would you like to be added:
A script to handle cleanup of the VMs that were renamed after they were moved in an AppFlows Failover event triggered while the source site was still online. The VMs are all renamed to Deprecated_* and can be safely removed to recover storage capacity in the source site once the health of the VMs created in the target site have been confirmed.
Why is this needed:
There is no function in AppFlows to delete the deprecated VMs.
