This commit provides the capability to install a
custom admin command handler for NVMF.
It can be used to implement or replace NVMe admin commands that
are currently not handled by the NVMF subsystem.
The handler implementation is pretty generic and the handler function
has to figure out what to do with the command based on the bdevs
that are configured for the subsystem.
In cases where admin commands need to be forwarded to an NVMe bdev,
the commit provides functions that allow access to the underlying bdev.
There is an example handler in lib/nvmf/custom_cmd_hdlr.c.
