Now the auto-added resources (items, triggers) can not be deleted. Only graph can be manually deleted - i think tis is bug.

Need to come up with a mechanism for automatic/manual removal of obsolete resources.
By obsolete, I mean:
resources that belong to the prototype, but is no longer discovered (for example we delete VLAN);
resources that have ceased to pass through the filter of the macros (various examples).
This should be an option in the settings of the rule - whether to delete obsoleted resources automatically.

I do not have a clear vision of how it should look, but I think that should be able to manually remove these obsolete resources, for example they should be made available for manual deletion (not obsolete resources should stay unavailable for deletion). This is the case if automatic deletion is not enabled.

as discussed with Aleksandrs Saveljevs i mark this issue as "blocker"
