This adds docs for all of ESQL's aggregation functions. Hopefully from here on out we can add the docs as we add new functions. I've created a few tagged regions in the aggs docs themselves so we can include them into the ESQL docs. --------- Co-authored-by: Abdon Pijpelink <abdon.pijpelink@elastic.co>

Can take any field type as input and the result is always a `long` not matter
|
|
the input type.
|

|
NOTE: There isn't yet a `COUNT(*)`. Please count a single valued field if you
|
|
need a count of rows.
