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.
