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.

6bb1d21489 Do not repartition cachelines in WO read 
WO cache mode should not repartition cachelines nor affect cacheline
status in any way when servicing read. Reading data from the cache
is just an internal optimization. Also WO cache mode is designed to
be used with partitioning based on write life-time hints and read
requests do not carry write lifetime hint by definition.

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.
