Point messenger, mesh-watcher, restic and mesh-issues away from the controller

The controller is not placed (ADR 0590): messenger no longer treats it as
a condition owner or a walk's subject, mesh-watcher reads only where the bus
runs, restic tells the operator to compose the machine or set config through
the seats that do it now, and mesh-issues' examples name a placed repository.
mesh-issues keeps mesh-controller among its owners: issues located there,
issue 1126 among them, and route-proxy until it moves, still name it
(issue 1126 B11).
