Consolidate handler tracking (#49338)

* Consolidate handler tracking
  -  Remove unused code. ci_complete
  - unit test fixes. ci_complete
  - Restore previous behavior of matching a single handler
  - when notifying a host for a handler, return True if it was added, False otherwise, to reduce copied logic
  - rename funcitons for clarity. ci_complete
  - Remove handler logic for static includes which was disabled previously
