60a6da7ee6 Extend alock API with entries_count method 
Right now alock assumes that number of locks taken will equal number of
core lines. This is not the case in pio, where only parts of metadata
are under locks. If pio request overlaps locked and not-locked metadata
section it will have different core lines number and awaited locks
number. To remedy this discrepancy additional method which gets count of
locks that will be taken/waited on is added to alock API.

3d83e1f004 pyocf: more generic erorr device volume

inheriting from RamVolume. This way error injection layer can be added

ad7a40feaf Use internal implementation of DIV_ROUND_UP 
It's required, because environments other than Linux kernel may not define
their own DIV_ROUND_UP. Moving it to env would just generate boilerplate,
because its implementation is trivial and portable.

Instead add params to control whether to construct and register

Additionally introducing Cache method to register additional I/O

cd4d894348 acp: skip the first bucket on recovering acp 
Since the threshold for the first bucket is always zero and the condition to
exit from the loop is never met in the first iteration it is save to start
iterating from `1`

This change is meant to avoid confusing static code analyzers
