Feat bulk locking (#1422)

* Feat: Multi-lock capabilities add to config

* wip: RPC.rs fixes, new combinatoric

* wip: changes

* chore: More things that are bulk

* fix: Saving

* chore: Remove a dyn object

* chore: Add tests + remove unused

* Fix/feat  bulk locking (#1427)

* fix: health check

* fix: start/stop service

* fix: install/uninstall services

* chore: Fix the notifications

* fix: Version

* fix: Version as serde

* chore: Update to latest patch db

* chore: Change the htLock to something that makes more sense

* chore: Fix the rest of the ht

* "chore: More ht_lock":
