5dd09e823b Initialize promotion policy before cleaning policy. 
If cleaning policy didn't have init() function,
   '_ocf_mngt_init_instance_load_complete' returned early and promotion policy
   wasn't initialized at all.

4f04b2762f Simplified stop path for cache detached case 
When cache is detached we cannot assume there is a management
queue created. This change introduces simplified cache stop
path, performing all the necessary deinit without using
IO queues.

aec01f216c Revert "Disallow ocf_cache_mode_max in io_class config" 
This reverts commit 5ad5c521df.

This change broke setting IO-classes with allocation. We use max as a
special value to indicate that the partition should use cache global
caching mode.

82e8c55f4a Write-only cache mode 
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.

7165bc16c3 Add kick function for cleaner 
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.

8391300bc8 Set core_id during load if user did not specify one 
If cfg->core_id is OCF_CORE_MAX and that core matches the UUID of
existing not opened one, then set cfg->core_id to id of that core.

This is useful when loading cache from metadata: if user does not store
the ids of cores but relies on OCF to assign them, there is no need to
not reassign them on load.

Previus behaviur when cfg->core_id != id of core with matching UUID is
maintained.
