Add asynchronous work API to the network manager

Browse Source 
The libuv has a support for running long running tasks in the dedicated
threadpools, so it doesn't affect networking IO.

This commit adds isc_nm_work_enqueue() wrapper that would wraps around
the libuv API and runs it on top of associated worker loop.

The only limitation is that the function must be called from inside
network manager thread, so the call to the function should be wrapped
inside a (bound) task.
