Users can specify the core for each subsystem and the acceptor listen routine
to run on different cores for performance consideration.

It is not currently configurable, but this will allow us to make the
discovery subsystem have config options (e.g. which lcore to run on).

Replace use of the newly-deprecated rte_mempool_count() with the new
name, rte_mempool_avail_count().
Also add a compatibility wrapper so that builds against older DPDK
versions still work.

These can be simplified and merged into the subsystem.
Remove the concept of mappings from subsystems and replace
it with a list of hosts and ports. The host is optional -
not specifying a host means any host can connect.

pool was initialized (which is already checked internally), and shutdown
just called spdk_nvmf_shutdown_nvme(), which we can call directly.
