OpenCAS continue to work after one of many cores fails
1. Start cache.
2. Add core1 to previously created cache.
3. Add core2 to previously created cache.
4. Fill cache with pages from core1.
5. Fail core1.
6. Check if core2 is able to use cache.

Test for preserving partitions from core device.
Test for preserving partitions at core device, which were made on exported object,
after stopping cache.
Also added two fields to 'Core' class which allows it to use 'create_partitions' function.

Add IO stress tests for small CAS devices with 1 or 4 cores for every cache mode
and cache line size and with every cleaning policy for WB and WO modes.

Rename set_statistics_deprecated to set_statistics_flat, as flat
statistics are sometimes more useful and actually not deprecated.

total_seconds() method from Python's datetime class outputs a Float
precision number which for some numbers multiplied by 10^n gives wrong
values.
total_seconds() method from attotime class wraps a native timedelta
object and outputs a Decimal precision number which fixes this issue.
