07c639cdec nvmf: Create poll groups on their respective cores
Previously, all of the poll groups were created on the
core doing the configuration. However, creating poll groups
will eventually construct the I/O channels, and that must
be done on the core we plan to use the poll group on.

db3edeb341 nvmf_tgt: Rewrite initialization as a state machine
This is about to become a hot mess of asynchronous operations,

d97476efdf iscsi: shutdown iscsi library as part of subsystem fini path
With the new asynchronous subsystem finish framework, we can
drive shutdown of existing connections as part of the subsystem
finish path instead of a separate spdk_iscsi_shutdown function
called as the shutdown function in response to SIGINT.

This is a step towards enabling a single target app that
supports multiple protocols (i.e. iSCSI + vhost + NVMe-oF).

fbb9430ec4 app: add spdk_app_parse_args()
This is a helper function that eliminates a lot of
duplicated code in our target applications, specifically
around common command line argument parsing and usage
messages.  This patch only moves the iscsi, nvmf and
vhost targets to use this function, but there are other
test/example applications that could also take advantage
of it to reduce duplicated code and improve consistency.

4bcfef0021 rpc: remove rpc subsystem
RPC is core functionality for SPDK applications and should always
be initialized last (after all subsystems have been initialized).
So make RPC a first class citizen and integrate it with the
app framework directly instead of making it an "optional" subsystem.
Then we initializing it after all subsystems have completed
initialization, and tear it down before tearing down subsystems.

We can also do some other cleanup while here - for example, reactors
are already started when spdk_rpc_initialize() is called, so remove
the extra event that was added during initialization since this is no
longer needed.

7ea544b46a nvmf: move poll groups to public API
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.

df7cf89394 iscsi, vhost, nvmf: allow running without config file
If the default config file does not exist, keep the
app's config_file options field as NULL, so that the
app code will not fail when trying to open a non-existent
file.

Also leverage the recent iSCSI and NVMe-oF refactoring,
to just skip trying to read config file parameters if no
config file exists (or the requisite section in the config
file is not present).  vhost already handled this so it did
not need to be modified.

31d033f944 nvmf: Transports are no longer global
Create one transport per nvmf target. Today, there is just
one global nvmf target, but this paves the way for multiple.

1d304bc5d8 nvmf: Rename spdk_nvmf_conn to spdk_nvmf_qpair
Match the terminology used in the NVMe-oF specification,
which is queue pair. For the RDMA transport, this maps to
an RDMA queue pair, but may map to other things for other
transports. It still is logically a "connection" from
a networking sense.

03788f93df nvmf: Rename spdk_nvmf_session to spdk_nvmf_ctrlr
This is just a rename - the functionality hasn't changed.
Use the same terminology as the specification (which is controller)
so those familiar with the specification can more easily
approach the code base.

This is still conceptually equivalent to a "session" in the
networking sense.

tracked traddr, trsvcid, trtype, etc. and use a trid.
