aa4622cc01 Make core remove error recoverable 
First try to clean only the mapping. This operation does not require any
rollback, so even if flushing collision fails, core object is still
intact. In case of error we inform user that core was not removed by
returning new error code (-OCF_ERR_CORE_NOT_REMOVED).

After flushing collision succeeds we remove core from metadata and
flush superblock at the end. At that point the core is fully removed
from OCF and even if superblock flush error occurs there is nothing we
can do about it, so we just return the error code.

17eddab094 pyocf: queue settle functionality 
Queue settle is a mechanism to wait for all OCF processing
on a given queue to finish.

In some tests simply waiting for I/O to finish is not enough. Most
notably some statistics are potentially incremented after user triggered
I/O is finished. This is due to asynchronous nature of I/O operations
and OCF approach to statistics update, where only eventual consistency
is guaranteed without explicit mechanism available to query whether
the final state is reached yet. However it is fully in the adapter power
to determine this, as OCF executes in context of API calls from the
adapter (like I/O submission, ocf_queue_run, ocf_cleaner_run, management
operations) and I/O completion callbacks. Queue settle is a mechanism to
assure ocf_queue_run is not being executed by the thread associated with
a queue.

With queue settle mechanism it is straightforward for the adapter to
wait for cache statistics to reach fixed values:
1. wait for all I/O to OCF to finish
2. settle all I/O queues
3. make sure background cleaner is not active
