GCC/Clang sanitizer can be used together with PyOCF to catch some errors during
testing.
CC was purposely removed from the Makefile. It always points to GCC on Linux
by default. This allows to change the compiler and its options during the run

Previously every created queue was added to io_queues list, which
made mngt_queue being used in ocf_parallelize. Change mngt_queue creation
