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.

7de56940a4 Move ocf_request from utils 
ocf_request has always been first class citizen in OCF,
so lets place it along with another essential objects.

91e0345b78 Implement asynchronous attach, load, detach and stop 
NOTE: This is still not the real asynchronism. Metadata interfaces
are still not fully asynchronous.

e53944d472 Dynamic I/O queue management 
- Queue allocation is now separated from starting cache.
- Queue can be created and destroyed in runtime.
- All queue ops accept queue handle instead of queue id.
- Cache stores queues as list instead of array.

506f0aa975 Add more missing io_set_queue 
Propagate id of ocf_queue for discard io

This resolves the issue of
  bottom adapter always getting an ocf_io with io_queue = 0,
  no matter from which queue function to bottom adapter was called

This is a follow up on e69894e398
