TT#8704 Implement peer probing.

* Add probe column to provisioning.voip_peer_hosts
* Add trigger to populate kamailio.dispatcher on active probing
* Fix kamailio.version table to version 4 of dispatcher table to
  use the attrs column.
* Write peerid (used for routing) and also peername and peergid
  (used for monitoring) into dispatcher attrs
* Only enable probing if peer is enabled
