Rafal Stefanowski 8fcb8b966d bdev/ocf: Improve cache line size handling
- Use consistent cache line size units in KiB across RPC calls
and config files. The KiB units are much easier to use then
the bytes units and are more human readable.
- Properly handle cache start when cache line size is incorrect.
- Add test to check if cache line size value is reported correctly.
- Add cache line size info to JSON RPC documentation.

Fixes #1858
