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.

Automatic GROUP BY to disk (max_bytes_ratio_before_external_group_by)
...
Simpler then max_bytes_before_external_group_by, that allows you not to
think about memory consumption of the query, and can be set globally to
i.e. 0.5 so that the external aggregation will be enabled once the
memory usage reaches the 50%.

varPop doc latex formula added
...
- There is a latex formula in the documentation of the [covarPop](https://clickhouse.com/docs/en/sql-reference/aggregate-functions/reference/covarpop ) method, which is quite similar to varPop method.
- In Russian docs there are formulas both for [varPop](https://clickhouse.com/docs/ru/sql-reference/aggregate-functions/reference/varpop ), and [covarPop](https://clickhouse.com/docs/ru/sql-reference/aggregate-functions/reference/covarpop ).
Therefore, for consistency, it is suggested to add formula here too.

window-functions doc typos fix
...
- A forgotten closing parenthesis ] has been added.
- The alias "teamMax" is less confusing for max (salary) than "teamAvg". This is probably the result of copying & pasting from the previous part of the document.
