[watcher][core] Resignation from Watcher core

Dear all, Unfortunately I have had increasingly little available free time to spent on the Watcher project over the years. Combined with loss of access to a test environment to debug an actual Watcher deployment for which it has become apparent it will not be reinstated. These combined events inhibit me from effectively making and reviewing patches. As of such I feel it is only right to resign as Watcher core reviewer. I will remove my roles from opendev and launchpad where appropriate as well as remove myself as reviewer from any pending patches. Kind regards & stay safe, Corne (Dantali0n)
