feat: Teach InfluxQL how to plan an aggregate query (#7230)
* feat: Display failed query

Allows a user to immediately identify the failed query.

* feat: API improvements to InfluxQL parser

* feat: Extend `SchemaProvider` trait to query for UDFs

* fix: We don't want the parser to panic on overflows

* fix: ensure `map_type` maps the timestamp data type

* feat: API to map a InfluxQL duration expression to a DataFusion interval

* chore: Copied APIs from DataFusion SQL planner

These APIs are private but useful for InfluxQL planning.

* feat: Initial aggregate query support

* feat: Add an API to fetch a field by name

* chore: Fixes to handling NULLs in aggregates

* chore: Add ability to test expected failures for InfluxQL

* chore: appease rustfmt and clippy 😬

* chore: produce same error as InfluxQL

* chore: appease clippy

* chore: Improve docs

* chore: Simplify aggregate and raw planning

* feat: Add support for GROUP BY TIME(stride, offset)

* chore: Update docs

* chore: remove redundant `is_empty` check

* chore: PR feedback to clarify purpose of function

* chore: The series_sort can't be empty, as `time` is always added

This was originally intended as an optimisation when executing an
aggregate query that did not group by time or tags, as it will produce
N rows, where N is the number of measurements queried.

* chore: update comment for clarity
