Added a priority queue for the request instead of push front

Browse Source 
Now the request can be pushed to a high priority queue (instead of ocf_queue_push_req_front)
and to a low priority queue (instead of ocf_queue_push_req_back).
Both functions were merged into one function (ocf_queue_push_req) and instead of the
allow_sync parameter there is now a flags parameter that can be an OR combination of
OCF_QUEUE_ALLOW_SYNC and OCF_QUEUE_PRIO_HIGH
