[pve-devel] [PATCH ha-manager 1/2] fix #6613: update rules containing the resource to be deleted

[Michael Köppl]

If the purge param is set, the resource that is deleted is also removed
from any rules referencing it. In the case that a resource is removed
that is also the last resource in a rule, the rule is also removed if
the purge option is enabled. This avoids rules remaining in the rules
config if their resources no longer exist.
