This patch fixes submission of partial IOs in bottom adapter
Existing check (if offset > 0) was not sufficient to detect partial IOs
because there could be an IO with offset = 0 but length < total size of iovs.
This patch changes the check, but also free operation on completion
because now the old free does not cover all situations when we allocate iovs.
`Partial IOs` are the IOs handled by bottom adapter
which specify only part of the internal iovs vector.
So their length is less that the length of internal iovs vector.
They exist because sometimes parts of single IO from top adapter
need to be sent to different locations.
Also, in general, IOs initiated by OCF (such as cleaner IOs) are represented
as single big iov that is submitted by parts in form of 'Partial IOs'.

Implement metadata probe functionality to load cache state
from disk.
During metadata probe, we inspect UUIDs of core devices
and create vbdev configurations based on them.
Then, to start vbdev, we use load path (loadq = true).
After this change persistent metadata is officially supported,
we can save and restore cache state from persistant storage.
WriteBack mode is now safe to use in respect to unexpected shutdowns,
because all information about dirty data is also restored during cache load.

Cleaner usually runs every ~20 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

WriteBack mode is fully functional after this change,
but persistent metadata support is required to use it for production.
Cleaner will run on management thread for now.

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.

Move last step of register chain to the top because it is arguably more readable.
This should not be done in previus patch because it spoils the gerrithub diff.

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.

Two quick updates, support dequeueing more than 1 IO at a time which
is now more likely given that we can queue up compression operations
(others can come in qhile one is on the queue).
Dropped the max inflight value as it was in there as a palceholder
and now it makes sense to give it a sane value. Also updated the value
passed to reduce to signal an error.
UT for the poller will come in the next patch...
