Implement pyocf adapter with sample OCF test

Browse Source 
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
