If ctrlr_loss_timeout_sec is set to -1, reconnect is tried repeatedly
indefinitely, and I/Os continue to be queued.
This patch adds another option fast_io_fail_timeout_sec, a flag
fast_io_fail_timedout to nvme_ctrlr.
If the time fast_io_fail_timeout_sec passed after starting reset,
set fast_io_fail_timedout to true not to use the path for I/O submission.
fast_io_fail_timeout_sec is initialized to zero as same as
ctrlr_loss_timeout_sec and reconnect_delay_sec.
The name of the parameter follows the famous DM-multipath, its fast_io_fail_tmo.

Previously reconnect retry was not controlled and was repeated indefinitely.
This patch adds two options, ctrlr_loss_timeout_sec and reconnect_delay_sec,
to nvme_ctrlr and add reset_start_tsc, reconnect_is_delayed, and
reconnect_delay_timer to nvme_ctrlr to control reconnect retry.
Both of ctrlr_loss_timeout_sec and reconnect_delay_sec are initialized to
zero. This means reconnect is not throttled as we did before this patch.
A few more changes are added.
Change nvme_io_path_is_failed() to return false if reset is throttled
even if nvme_ctrlr is reseting or is to be reconnected.
spdk_nvme_ctrlr_reconnect_poll_async() may continue returning -EAGAIN
infinitely. To check out such exceptional case, use ctrlr_loss_timeout_sec.
Not only ctrlr reset but also non-multipath ctrlr failover is controlled.
So we need to include path failover into ctrlr reconnect.
When the active path is removed and switched to one of the alternative paths,
if ctrlr reconnect is scheduled, connecting to the alternative path is left
to the scheduled reconnect.
If reset or reconnect ctrlr is failed and the retry is scheduled,
switch the active path to one of alternative paths.
Restore unit test cases removed in the previous patches.

We noticed the difference between the SPDK 21.10 and the latest master
in a test.
The simplified scenario is as follows:
1. Start SPDK NVMe-oF target
2. Run bdevperf for the target with -f parameter to suppress exit
on failure.
3. Kill the target after I/O started.
With the SPDK 21.10, bdevperf retries failed I/Os and exits after
the test time is over.
With the latest SPDK master, bdevperf hungs and does not exit even
after the test time is over.
The cause was as follows:
reset ctrlr is repeated very quickly (once per 10ms by default) and hence
I/Os were queued infinitely because nvme_io_path_is_failed() returned
false if nvme_ctrlr is resetting.
We should queue I/O when nvme_ctrlr is resetting only if reset is throttoled
and fail-fast for the repeated failures is supported.
Hence in this patch, fix the degradation and remove the related unit
test cases.

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

It is possible to repeat get_io_channel later but
there is no such indiciation for the application,

bdev_nvme_delete() calls bdev_nvme_failover() with remove=true to remove
nvme_ctrlr->active_path_id. However bdev_nvme_failover() returns zero
if nvme_ctrlr->failover_in_progress is true. bdev_nvme_failover() may
return zero even if it does not remove nvme_ctrlr->active_path_id.
The following will be better.
bdev_nvme_failover() returns -EBUSY if nvme_ctrlr->resetting is true,
and the caller repeats calling bdev_nvme_failover() until the target trid
becomes alternative path or bdev_nvme_failover() returns zero.
To do that, the failover_in_progress flag is not necessary any more.
Removing the failover_in_progress will also simplify the following

When resetting ctrlr, adminq is disconnected first. If adminq is disconnected,
admin passthrough request is rejected with -ENXIO.
But resetting ctrlr may succeed. If resetting ctrlr succeeds, adminq is
connected again, and admin passthrough request will be
submitted successfully.
On the other hand, if ctrlr is failed, admin passthrough request is
rejected with -ENXIO. But when resetting ctrlr, ctrlr is set to unfailed.
Hence bdev_nvme_admin_passthru() skips any ctrlr which is resetting
or failed, and calls bdev_nvme_admin_passthru_complete() with -ENXIO
if no available ctrlr is found.
bdev_nvme_admin_passthru_complete() queues admin passthrough request

The NVMe bdev module queues retried I/Os itself now.
bdev_nvme_abort() needs to check and abort the target I/O if it
is queued for retry.
This change will cover admin passthrough requests too because they
will be queued on the same thread as their callers and the public
API spdk_bdev_reset() requires to be submitted on the same thread
as the target I/O or admin passthrough requests.

The completion status of spdk_bdev_abort() is SPDK_BDEV_IO_STATUS_SUCCESS
or SPDK_BDEV_IO_STATUS_FAILED if it is successfully submitted.
In the generic bdev layer, spdk_bdev_abort() does not update cdw0 but
just set SPDK_BDEV_IO_STATUS_SUCCESS or SPDK_BDEV_IO_STATUS_FAILED.
In the NVMe bdev module, for the abort request, spdk_bdev_io_complete()
is called instead of spdk_bdev_io_complete_nvme_status() and the
completion status is SPDK_BDEV_IO_STATUS_SUCCESS or
SPDK_BDEV_IO_STATUS_FAILED.
So let's skip updating cdw0 and call spdk_bdev_io_complete() directly
with SPDK_BDEV_IO_STATUS_SUCCESS or SPDK_BDEV_IO_STATUS_FAILED if
bdev_nvme_abort() does not find the target I/O in any ctrlr.
The next patch will fix spdk_bdev_io_get_nvme_status() for the abort
I/O.

For clarification, rename retry_count to transport_retry_count of

If ANA state is inaccessible or qpair is disconnected, I/O cannot
be submitted.
But if qpair is connected, ANA state may become accessible, or if
qpair is disconnected, it may become connected via resetting.
Hence even if find_io_path() returned NULL, queue I/O and retry it
one second later if qpair is connected or ctrlr is resetting.
Sort retried I/Os by expiration values in ticks, and activate a timed
poller per nvme_bdev_channel only if there is any retried I/O. So
the poller function bdev_nvme_retry_ios() always returns BUSY because
if the poller runs earlier than the closest retried I/O or runs when
there is no retried I/O, it is more like a bug of the framework.
