Roman Nozdrin 72e264e8ef MCOL-5199 This patch solves the overal performance degradation introduced with a new way of char columns hashing 
in aggregation code
The patch disables padding that forces hasher to calculate over the whole 2k buffer. This patch also moves hashing code
into the common place where it belongs.
