Description of problem:
When cancelling a warm migration plan with a single rhel8 VM, the CBT snapshots remain on the VMware source VM.
Version-Release number of selected component (if applicable):
CBT snapshots should be removed after the warm migration is cancelled
This seems to be a generic problem of not removing the snapshots on source after plan is cancelled, and not related to a specific migration plan/VMs in the plan.
The fix should be in build hco-bundle-registry-container-v2.6.3-9.
