Adapter can provide ops for data type deinitialization, if any additional
operations are required on deinitialization procedure.

Promotion policy is supposed to perform ALRU noise filtering by
eliminating one-hit wonders being added to cache and polluting it.

Write-only cache mode is similar to writeback, however read
operations do not promote data to cache. Reads are mostly serviced
by the core device, only dirty sectors are fetched from the cache.

ocf_kick_cleaner() allows to perfom cleaning immediately.
Nop cleaning policy now returns new 'OCF_CLEANER_DISABLE' macro which indicates
that cleaing shouldn't be performed. To enable it back, ocf_kick_cleaner()
should be called.

As non-interruptible flushes are no longer triggered from OCF
internals, we can get rid of "interruption" argument and let
adapters handle it themselves.

Due the aggresive security checks in compiler 'printf' might be substituded with
'__printf_chk'. However it does not differentiate whether substituted string is
library function call whether field in structure.
By renaming field we prevent it to be unintentionally subustituted by the
preprocessor.

Fix some instance tracking to prevent Python-side objects from leaking
buffers.
Also, reduce min size of Cache instance (real minimum should be around ~~19MiB,
but we need to make it more deterministic and 20 MiB seems to be reasonable).
Still some stuff left to do, but it needs more investigation and, for
now, this should suffice just to enable some form of CI.

This pointer is used to provide optional volume specific data
from the user down to bottom volume open callback. volume_params
is provided to OCF in ocf_mngt_cache_device_config.volume_params.

NOTE: This is still not the real asynchronism. Metadata interfaces
are still not fully asynchronous.
