f461f3c62e Extend probe informations with cache name. 
Since ocf requires loading cache with the same name as it was stopped, it should
also allow to read name from metadata.

When loading cache metadata, it should be started with exactly the same name as
it was running previously. Otherwise load should fail and return newly added
error code.

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.
