a504821302 pyocf: separate get_conf() from stats in Cache 
Configuration parameters are available in standby mode, while
stats are not. Need to separate the two.

3d83e1f004 pyocf: more generic erorr device volume 
Make ErrorDevice a wraper over any type of volume rather than
inheriting from RamVolume. This way error injection layer can be added
over any type of volume.

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

81fc7ab5c5 Parallel eviction 
Eviction changes allowing to evict (remap) cachelines while
holding hash bucket write lock instead of global metadata
write lock.

As eviction (replacement) is now tightly coupled with request,
each request uses eviction size equal to number of its
unmapped cachelines.

Evicting without global metadata write lock is possible
thanks to the fact that remaping is always performed
while exclusively holding cacheline (read or write) lock.
So for a cacheline on LRU list we acquire cacheline lock,
safely resolve hash and consequently write-lock hash bucket.
Since cacheline lock is acquired under hash bucket (everywhere
except for new eviction implementation), we are certain that
noone acquires cacheline lock behind our back. Concurrent
eviction threads are eliminated by holding eviction list
lock for the duration of critial locking operations.

eeda1f3f0f Unify type of dirty_for in info structs 
Reformat function that calculates how long cache/core is dirty
Update `dirty_for` types in functional tests

Values stored in info structs fields (both in cache and core structs)
are unsigned 64-bits ints but `dirty_for`s were unsigned 32-bits ints.

Use existing function to transform returned value to seconds.
Replace seconds stored in metadata with seconds.
Replacement was done if old value of replaced field was equal to zero.
Acquiring monotonic high precission timestamp is potentially
slow and it makes sense to compare the field's value
to zero before calling atomic function.
