Previously the NVMe bdev module had completed the outstanding reset and
then canceled pending resets. This was complex.
On the other hand, the generic bdev layer cancels pending resets
and then completes the outstanding reset.
Following the generic bdev layer simplifies the code and makes us easier
to control retry reset, delay retry reset by a few seconds, or stop retry
after repeated failures and then delete ctrlr.
Update unit tests accordingly.

Previous patches (5363eb3c) tried to work around the
32-bit unmap and write_zeroes LBA counts by breaking
up larger operations into smaller chunks of max size
UINT32_MAX lba chunks.
But some SSDs may just ignore unmap operations that
are not aligned to full physical block boundaries -
and a UINT32_MAX lba unmap on a 512B logical /
4KiB physical SSD would not be aligned. If the SSD
decided to ignore the unmap/deallocate (which it is
allowed to do according to NVMe spec), we could end
up with not unmapping *any* blocks. Probably SSDs
should always be trying hard to unmap as many
blocks as possible, but let's not try to depend on
that in blobstore.
So one option would be to break them into chunks
close to UINT32_MAX which are still aligned to
4KiB boundaries. But the better fix is to just
change the unmap and write_zeroes APIs to take
64-bit arguments, and then we can avoid the
chunking altogether.
Fixes issue #2190.

- they are in the same NVM subsystem,
- they are in different ctrlrs,
- they are identical.
Additionally, if we add one or more namespaces to an existing
nvme_bdev and there are active nvme_bdev_channels, the corresponding
I/O paths are added to these nvme_bdev_channels.
Even after this patch, ANA state is not utilized in I/O paths yet.

This patch replaces the synchronous `spdk_nvme_detach()` calls with its
asynchronous counterparts in the controller unregister path.
An additional poller is introduced to periodically poll the NVMe driver
for detach completion. Once the detach is completed, the poller is
unregistered and the nvme_ctrlr is destroyed. The poller uses the same
period (1ms) as the async probe poller.
Since reset and detach cannot happen at the same time, reset_poller was
renamed to reset_detach_poller and it can now store the pointer either
to the reset or detach poller, depending on the circumstances.

We have _is_core_over_limit() which determines if a core is
currently over its busy:total tsc ratio. We use this to determine
if we need to move threads off of a core that is too busy.
But when we pick a core to move a thread *to* we were allowing the
dst core to fill to 100%, rather than the SCHEDULER_CORE_LIMIT.
This patch fixes that, which has the nice effect of keeping
thread-to-core assignments much more stable when running
I/O workloads.

If a core has a very high busy percentage, we should
not assume that moving a thread will gain that
thread's busy tsc as newly idle cycles for the
current core.
So if the current core's percentage is above
SCHEDULER_CORE_BUSY (95%), do not adjust the
current core's busy/idle tsc when moving a thread
off of it. If moving the thread does actually
result in some newly idle tsc, it will get adjusted
next scheduling period.

For the src thread, add the busy_tsc of the thread
we are moving to the idle_tsc of the current core.
This is consistent with how are accounting for the
cycles in the target core too.
We will disable the load_balancing.sh script for now.
We will reenable it later in this patch set once
a few other changes are made, along with some updates
to the load_balancing.sh script based on the changes
made in this patch set.

This patch enables us to aggrete multiple ctrlrs in the same NVM
subsystem into a single bdev ctrlr to create multipath.
This patch has a critical limitation that ctrlrs which are aggregated
need to have no namespace. Hence any nvme bdev is not created.
However it will be removed in the next patch.
The design is as follows.
A nvme_bdev_ctrlr is created to aggregate multiple nvme_ctrlrs in
the same NVM subsystem. The name of the nvme_ctrlr is changed to be
the name of the nvme_bdev_ctrlr.
NVMe bdev module has both the failover feature and the multipath
feature now. To choose which of failover or multipath to use, add an new
parameter multipath to the RPC bdev_nvme_attach_controller.
When we attach a new trid to the existing nvme_bdev_ctrlr, we use the failover
feature if multipath is false, we use the multipath feature if multipath is
false.
nvme_bdev_ctrlr has a list for nvme_ctrlr and it is guarded by the
global mutex. Callers can query nvme_ctrlrs from a nvme_bdev_ctrlr via
trid as a key. nvme_bdev_ctrlr is not registered as io_device.

Previously, if an I/O qpair is disconnected, we tried reconnecting
the qpair. However, this reconnect operation was very likely to fail
and will not match the upcoming asynchronous connect/reconnect
operation. We need an extra callback to make this reconnect operation
asynchronous, but we do not want to have it.
Hence if an I/O qpair is disconnected, we free the I/O qpair and then
reset the corresponding nvme_ctrlr immediately. If the admin qpair is
also disconnected, the nvme_ctrlr is reset immediately. However this
event may never happen. So we do not wait for the error of the admin
qpair.
The NVMf host may disconnect connections by itself intentionally.
In this case, resetting the nvme_ctrlr will surely fail. But resetting
the nvme_ctrlr frees all I/O qpairs of the nvme_ctrlr and these I/O
qpairs are not created again until resetting the nvme_ctrlr succeeds.
Resetting the nvme_ctrlr once at most is more efficient than repeating
reconnecting the I/O qpair. So this change is valuable even for such
intentional disconnection. However, it is helpful to know the event that
I/O qpair is disconnected. Hence change DEBUGLOG to NOTICELOG in the
disconnected callback. The disconnected callback is not repeated, and
we do not need to worry about NOTICELOG flooding.
Refine the unit test case to verify this change.
