Implement management queue for asynchronous management that is provided
in new OCF API. This is a neccessery step to be able to implement
metadata support.
OCF submodule was updated to get management queue functionality
It has to be done in this patch because OCF module will not work
otherwise.

OCF queue list needs to be managed synchronously.
This patch uses our own mutex to achieve that because we cannot rely on
ocf_mngt_cache_lock() as it may produce deadlocks when using
cleaner.
Alternative way would be to use trylock, but
we need to register a poller for it and do locking concurently
which doesn't seem to be possible in callbacks of io channel.
We agreed with OCF team that we are going to change this part
when OCF will deliver safe ocf_mngt_cache_lock() function.
This patch fixes a very rare failure on our CI that looked like this:

Use new trylock API to prevent lockups when using OCF cleaner.
Starting and stoping OCF bdev becomes asynchronous with this patch.
Using trylock means that we have to poll function that does locking each
time we want to initiate some operation on cache instance.
This is the reason why management functions become asynchronous.
Each management operation now has a _poll() operation associated with it.
_poll() uses trylock and continues when cache is locked.

This patch is a preparation for adopting ocf_cache_trylock() function.
Register OCF bdev path uses vbdev_ocf_mngt_ interface now
Register stays synchronous blocking operation in this patch,
but with adoption of ocf_cache_trylock() function,
register will be asynchronous, in which case we
want to use mngt_ interface.
This series of OCF patches will enable WriteBack support for OCF bdev.
There is a lot of preparation before we will be able
to actually implement WriteBack.
Dependencies look like this:
- WriteBack
- Cleaner
- trylock
- Persistent metadata
- asynchronous management API
Cleaner is a background agent that does synchronization
of data between cache and its cores.
Cleaner usually runs every ~30 seconds to perform cleaning.
The synchronization is a simmilar operation to OCF management flushes.
We need cleaner for WriteBack because only WriteBack mode
produces dirty data that cleaner needs to deal with.
Cleaner requires adopting trylock() because in current version
cleaner uses management lock when performs cleaning,
which may lead to deadlocks if cleaner runs on
the same thread as management operations.
Peristent metadata is functionality of OCF
that allows to restore cache state after shutdown
We need persistent metadata in context of shutdown
with some data being dirty which may only happen
when using WriteBack mode
Support for persistent metadata requieres
asynchronous OCF API because in current version
we will have a deadlock during metadata initialization
because it is required to be done on different thread
than cache initialization.

We throttle the number of data_in operations per
connection. Currently after a read is completed,
we try to send more data_in operations since one
has just been completed.
But we are trying to send more too early. The data_in_cnt
doesn't actually get decremented until after the PDU is
written on the socket. So this results in a case
where data_in_cnt == 64, and all 64 read operations
complete before any of those 64 are actually transmitted
onto the TCP socket. There are no more read operations
waiting, so we won't try to handle the data_in list
again, and if none of these 64 resulted in a SCSI
command completing, then the initiator may not send us
any more read I/O which would have also kicked the data_in
list.
So the solution is to kick the data_in list after the
PDU has been written - not after a read I/O is completed
back from the SCSI layer.

The datain handling code path will set the LUN to
NULL if it finds a task's LUN has been hotremoved.
This could happen before the iscsi hotplug routine
actually gets a chance to run. If this happens,
one of these tasks doesn't actually get freed, and
then will be freed after the lun is closed -
causing a segfault in the bdev layer since it may
have a bdev_io associated with it.
Found by running the iscsi_tgt/fio test after
applying the next patch in this series.
There's more work needed in this hot remove clean up
path - currently we are just freeing a lot of PDUs
rather than completing them with error status when
a LUN is hot removed. But let's tackle that

bdev_raid.sh was using configuration file (bdev.conf.in)
made for blockdev.sh. Changes in that config file affected
the raid tests.
Since the test actually only used two malloc devices as
raid bases, switching to RPC makes it simpler clearer
to understand what is used in tests. Additionally
making raid tests standalone from blockdev.sh.

We have to process only the first call of destroy_raid_bdev RPC
for the same RAID bdev.
The existing flag destruct_called cannot be used for that purpose
because of the following reason.
destruct_called is set to true in both of
- destroy_raid_bdev RPC
- hot removal of any base bdev.
If destruct_called is set in destroy_raid_bdev RPC, destroy_raid_bdev
RPC must return immediately, but if destruct_called is set in hot
removal of any base bdev, destroy_raid_bdev RPC must go forward
with the current logic.
Hence add another flag destroy_started to struct raid_bdev and
use it.

In order to truly support multi-sgl inline requests in the RDMA
transport, we would need to increase the size of the
spdk_nvme_rdma_req object dramatically. This is because we would need
enough ibv_sge objects in it to support up to the maximum number of SGEs
supported by the target (for SPDK that is up to 16). Instead of doing
that or creating a new pool of shared ibv_sge objects to support that
case, just send split multi-sgl requests through the regular sgl path.

one at a time. With this new feature, it takes
