5a88ab2d61 Flush metadata collision segment on core remove 
If there is any dirty data on the cache associated with removed core,
we must flush collision metadata after removing core to make metadata
persistent in case of dirty shutdown.

This fixes the problem when recovery procedure erroneously interprets
cache lines that belonged to removed core as valid ones.

This also fixes the problem, when after removing core containing dirty
data another core is added, and then recovery procedure following dirty
shutdown assigns cache lines from removed core to the new one, effectively
leading to data corruption.

0dc8b5811c Store min and max ioclass size as percentage val 
Min and max values, keept as an explicit number of cachelines, are tightly
coupled with particular cache. This might lead to errors and mismatches after
reattaching cache of different size.

To prevent those errors, min and max should be calculated dynamically.
