In current code there is no possibility to remove ocf instance
permanently, even we call delete_ocf_bdev rpc command, on next examine
this instance will be loaded.
This patch introduces changes to delete_ocf_bdev rpc command. When we call
this command via rpc, core related to particular vbdev will be removed
from ocf cache before removing this cache instance. Thanks to that, on
next examine we will not detect this core in cache metadata and therefore
we will not create this instance on next load.
However, in any other situation, we will not touch metadata, so in case of
dirty shutdown/hot remove, on next load, we will recovery this instance.

Fixes#962
Issue mentioned above was caused by race between examine on ocf bdev
(which is partially asynhronous) and bdev delete.
This patch adds new ocf bdev state "starting" it means that register
procedure was started, base on this state, we are not allowing to
destruct vbdev during registering path.
Deleting of vbdev will be still possible on started vbdev or when
register procedure are not started yet.

Realted to #957
Normally we are using vbdev_ocf_qcxt allocated by spdk device (ctx_buf),
but after io_device_destroy_cb this context can be freed, so we allocate a
local copy to use for issuing requests on ocf bdev stop. Unfortunately,
in current code we are not freeing it, this patch fix that issue.

This is more accurate to what they are, and will make defining library
dependencies much simpler. This change in directory does not affect the
final placement of naming of libraries at the end of time.
