Drop the keeper's and config's take-over verbs with the controller's sources

mesh-sdk drops compare, take-over and hand-back from the keeper's and
config's seats (ADR 0590): there is no controller to compare with or hand
back to. mesh-conditions loses those verbs, its take-over key and asks;
mesh-config reads its own sources always and pull-declares is gone; and
mesh-hand-acts no longer names the controller's log (issue 1126).
