Title: Account operation memory by operation count to account empty

Currently delete operations are not accounted to live bytes as it has no columns. Im my case this leads to column families not flushed because they have 'no changes' (and futher OOMs). This patch fixes the problem by introducing per-operation overhead accounted. Note that it may be needed to reduce 1.25 parameter as 1.25 is the parameter that should account this overhead.
