As the below Bug #2018974 will not be resolved for MTV-2.2,
It needs to be documented that when deleting a migration plan,
cdi-Importer & migration pods and all related resources are not removed
See also this MTV-2.2 UI bug that will display a message on that in UI when deleting a plan:
Bug 2022651 - [UI] Add the Delete migration plan message that the related resources will remain
Once Bug #2018974 will be resolved, the Doc/UI message will need to change to notify the resources will be deleted.
+++ This bug was initially created as a clone of Bug #2018974 +++

After talking this over with Jeff, it's clear to me that we can't proceed with the finalizer-based solution I proposed. Jeff mentioned that MTC had the same problem they attempted a finalizer-based solution as well, but finalizers are inherently fraught with issues (race conditions preventing resources from being deleted, etc), and that approach was abandoned. Unfortunately, there's no alternative that would let us archive the plan upon deletion. We should document that the user must archive the plan before deleting it if they want the plan's resources to be removed, and perhaps we could have the UI warn before allowing an unarchived Plan to be deleted.
