If a backend needs to handle its own long-running threads on the side, it might
need to be notified to pause while a config modification is underway and when it
This is the case of the load balancer module, which registers itself as a module
and maintains its own threads and needs to know when a server (or even its own)

the hooks to pause and unpause the server, use them in bconfig.c and add two new
backend hooks that are consulted while this is happening.
