On `zebra` / `bfdd` shutdown we now clean up all client data to avoid
memory leaks (ghost clients). This also prevents 'slow' shutdown on
`zebra` sparing us from seeing some rare topotests shutdown failures
(signal handler getting stopped by signal).

This will make `bfdd` synchronize with its client when zebra dies or
bfdd is restarted.

When `bfdd` is enabled - which it is by default - re-route the PTM-BFD
messages to the FRR's internal BFD daemon instead of the external
PTM daemon.
This will help the migration of BFD implementations and avoid
duplicating code.
