8db93260ae Avoid adding mngt_queue to io_queues list 
Previously every created queue was added to io_queues list, which
made mngt_queue being used in ocf_parallelize. Change mngt_queue creation
API so that mngt_queue is not added to the list and doesn't have
unnecessary functionalities initialized.

Replace the pattern:
	completion = OcfCompletion([("err", c_int)])
	io.callback = completion.callback
	io.submit()
	completion.wait()
with:
	completion = Sync(io).submit()
Also, remove some redundant imports.

1bdf4a13ae pyocf: Improve volume instance lifecycle handling 
We need a strong reference to volume for as long as OCF has it open.
For that I changed instance tracking dictionary from weakvalue to
normal. This way I made sure that GC won't clean up Volume before its
closed.
