d06f376627 Alru cleaning policy improvement 
Instead of calling flush separatly for each IO class, it is called after
collecting number of dirty cache lines defined by user or after iterating
through all IO classes.

e5227cef89 Implement pyocf adapter with sample OCF test 
PyOCF is a tool written with testing OCF functionality in mind.
It is a Python3 (3.6 version required) package which wraps OCF
by providing Python objects in place of OCF objects (volumes, queues,
etc). Thin layer of translation between OCF objects and PyOCF objects
enables using customized behaviors for OCF primitives by subclassing
PyOCF classes.

This initial version implements only WT and WI modes and single,
synchronously operating Queue.

TO DO:

  - Queues/Cleaner/MetadataUpdater implemented as Python threads
  - Loading of caches from PyOCF Volumes (fix bugs in OCF)
  - Make sure it works multi-threaded for more sophisticated tests

9b9b965b55 Add cache locking functions in trylock variant 
- Add cache trylock and read trylock functions.
- Introduce new error code -OCF_ERR_NO_LOCK.
- Change trylock functions in env to return this code in case of
  lock contention.

[ENV CHANGES REQUIRED]
Following functions should return 0 on success or -OCF_ERR_NO_LOCK
in case of lock contention:
- env_mutex_trylock()
- env_rwsem_up_read_trylock()
- env_rwsem_up_write_trylock()

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.
