Jim Harris 59fdf4ce3a bdev_nvme: add bdev_nvme_start_discovery RPC
This patch adds the framework for a discovery
service in the bdev/nvme module.

Users can specify an IP/port of a discovery service.
The bdev/nvme module will connect to a discovery
controller, get the discovery log page, and then
register for AERs.  It will connect to each
subsystem specified in the initial log page.
AER completions will trigger fetching the log
page again, at which point new subsystems will
be connected to, or removed subsystems will be
detached.

This patch does the following:
* Adds the new start_discovery RPC
* Connects to the discovery controller
* Gets the discovery log page
* Registers for AERs
* Detach from discovery controllers at shutdown

Subsequent patches in this series will:
* Connect to subsystems listed in discovery log page
* Detach from subsystems that were listed in earlier
  discovery log pages but subsequently removed
* Add a stop_discovery RPC
