metricsql: support optional 2nd argument for rollup functions (#3841) 
* metricsql: support optional 2nd argument for rollup functions

Support optional 2nd argument `min`, `max` or `avg` for rollup functions:
 * rollup
 * rollup_delta
 * rollup_deriv
 * rollup_increase
 * rollup_rate
 * rollup_scrape_interval

 If second argument is passed, then rollup function will return only the selected aggregation type.
 This change can be useful for situations where only one type of rollup calculation is needed.
 For example, `rollup_rate(requests_total[5m], "max")`.
