942825146a Simplify _ocf_mngt_cache_deinit_services() 
Move flushing metadata outside cache_detinit_services(), so the function
can be shared between stop() and detach() without redundant ifs.

23abad76a8 Add script for running PyOCF with sanitization 
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
of the script
