Subject: coolio_fiber_spawn: decrease CPU usage for keepalive

Blindly resuming fibers every second is a waste of cycles, we
can use the ZZ hash in regular FiberSpawn to resume expired
fibers on an as-needed basis.

While we're at it, merge the keepalive-timeout class into the
heartbeat, there's no reason to have separate timers and
classes here.
