  doveadm director: Improve logging unexpected disconnections from director socket

Previously it just logged "failed", which wasn't very understandable.

  director: Delay calling state_change_callback() after user kick is finished

Otherwise it can get into recursive loop and cause problems.

  Log Message:
  -----------
  director: Avoid "ring sync timeout" errors when all backends are down

doveadm commands were failing with it. Also pending request failures were
logged as failing due to ring sync timeout, instead of because no hosts.

  Log Message:
  -----------
  director: Fix flush to kick the user also when all backends are down

The user's host can't change, because there are no other hosts. So add a
new parameter to force the kick anyway.
