Timestamp ranges come from "untrusted" inputs (via gRPC) and must not
lead to panics. The only case where this could happen is at `start >
end`. Let's just set `start = end` in this case. Reaonsing:
- Semantically this is a sound range, since this is only a somewhat
degenerated case of "empty".
- We already allow `start = end` to represent "empty" ranges.
- We already clamp (and therefore modify) `start` to the valid range.
Fixes https://github.com/influxdata/conductor/issues/1080.

InfluxQL queries can send (technically incorrect) ranges like this, meaning all time
but excluding the max nanosecond time.
Since this is an important case, we should handle it specially and use the optimized
'all time' handling for meta queries even though this is technically wrong in that
it does not filter out column names / measurement names at MAX_NANO_TIME exactly.
Closes: https://github.com/influxdata/conductor/issues/1072

* refactor: store per-file column set in catalog
Together with the table-wide schema and the partition-wide sort key, this should
be everything we need to read a parquet file directly into memory
without peeking any file-level metadata.
The querier will use this to directly load parquet files into the read
buffer.
**WARNING: This requires a catalog wipe!**

Changes the partitioner to always generate a partition key, even if the
column being used to partition doesn't exist. This doesn't functionally
change the batch partitioning output, but ensures we always have a
non-empty string for the partition key.
This commit changes the code base to use a new reference-counted
PartitionKey type wrapper, instead of passing a bare String around.
This allows the compiler to type check & verify usage of the partition
key, instead of passing a bare string around. By reference counting the
underlying string, we reduce memory usage for some use cases.
* feat: Change data type of catalog Postgres partition's sort_key from a string to an array of string
* test: add column with comma
* fix: use new protonuf field to avoid incompactible
* fix: ensure sort_key is an empty array rather than NULL
* refactor: address review comments
* refactor: address more comments
* chore: clearer comments
* chore: Update iox_catalog/migrations/20220607102200_change_sort_key_type_to_array.sql

* feat: `SortKey::size`
* feat: `FunctionEstimator`
* feat: querier RAM pool
Let's put all the caches into a single RAM pool, so we can at least
somewhat control RAM usage. Note that this does NOT limit the peak
memory during query execution though, but should at least stop unlimited
cache growth. A follow-up PR will add metrics.
* refactor: improve some size calculations
