87a106702b app/vmselect/promql: add aggr_over_time(("aggr_func1", "aggr_func2", ...), m[d]) function
This function can be used for simultaneous calculating of multiple `aggr_func*` functions
that accept range vector. For example, `aggr_over_time(("min_over_time", "max_over_time"), m[d])`
would calculate `min_over_time` and `max_over_time` for `m[d]`.
