Azat Khuzhin bdb39a6fef Change logic of automatic ORDER/GROUP BY to be based on available memory
- remove max_bytes_ratio_before_external_{order,group_by}_for_server
- change the way max_bytes_ratio_before_external_{order,group_by} works

Note, that it is not enough to transform ratio to bytes in
executeQuery(), since in this case it will not work for merges and
internal queries, plus, you have to reset them for Distributed engine
and update it for Merge/View/...

This patch also introduce some helpers (see MemoryTrackerUtils) and
adjust Aggregator::Params constructor to accept Settings object instead
of tons of arguments.
