[pve-devel] [PATCH ha-manager v3 06/15] config: delete services from rules if services are deleted from config

[Daniel Kral]

Remove HA resources from rules, where these HA resources are used, if
they are removed by delete_service_from_config(...), which is called by
the HA resources' delete API endpoint and possibly external callers,
e.g. if the HA resource is removed externally.

If all of the rules' HA resources have been removed, the rule itself
must be removed as it would result in an erroneous rules config, which
would become user-visible at the next read and parse of the rules
config.
