It's intended to be used in a context, where cache is not initialized
and the io_queue is not available yet.

Skip the ocf_io abstraction and get the data directly from the request.

This is meant to be used in atomic mode to avoid allocating huge buffers
for zeroing data on drive.

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.

This allows to create a Rio prototype object and the copy it for every
invocations so that some parameters can be overwritten without modifying
the prototype object itself.

Make sure end_offset is never generated as 0. Otherwise the last volume
in the range will not get any io, leading false negative test result.

Majority of management operations should be blocked for detached cache,
although adding and removing cores should be possible.

PyOCF needs to control random seed, to allow running tests with
pytest-xdist. Use local random object initialized with seed
from the config.

Make Volumes usable by both pyocf and OCF with clear open/_open split
and clean-up of instance/uuid tracking on C interface only.

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.
