Users can use RPC to add/remove a namespace to/from
existing NVMe controller, SPDK NVMeoF target will
generate an asynchronous event as an indication to
host when asynchronous event request is available.
While here, we also set the event with invalid log
identifier, so that the host doesn't need to clear
the event. Users can use Set Feature to disable
such event.

The NVMe spec states that nqn names are to be encoded in utf-8. The
prefixes of all nqn's are already required to be ascii by virtue of
their structure so they are already valid utf-8, but the user specified

The end goal is to have the application create one poll group per core.
Then each poll group will have a single CQ per network device and an I/O
channel per back-end storage device to poll.
This is just the first step toward that, which is to wire up the
creation of the per-core poll groups in the application.
Note that the app poll groups don't do anything yet. We'll need
additional library API changes to make the library use the existing poll
groups, rather than creating a new poll group per subsystem as we do
right now.

Previously we made cntlid globally unique as part of
a strategy for scaling connections that never panned
out. Now, we have a new strategy and don't need cntlid
to be globally unique, so relax the restrictions
and simplify the code.

This makes it easier to unit test the individual functions and also
easier to follow the logic.
These helpers will also be used in the upcoming Write Zeroes function.
Also cleans up the variable names to be consistent with the rest of the
code.

The current hot plug support assumes only one thread
can access a subsystem at a time, but now that we're
changing that this will need to be reworked. In the
interest of making it easier to change the threading
model, remove hot plug support temporarily. We'll add
it back in once the threading model changes are done.
