* refactor: do not override parquet file size in querier
This is going to be an issue when we actually rely on the size for
reading, see #5531.
* refactor: use selected file size mocking in compactor
Do not blindly override parquet file sizes for all subsystems.
This is going to be an issue when we actually rely on the size for
reading, see #5531.
* refactor: remove ability to override file sizes in catalog
Blindly overriding data for all subsystems is dangerous, because some
parts of our stack actually rely on the actual file size. See #5531.
* docs: explain `size_overrides`
And only allow setting this when no record batch or line protocol is
specified so that there isn't a way to create a parquet file with data
that has a mismatched row count.
* refactor: remove min_sequnce_number
* fix: typos
* fix: remove min_sequencer_number from new files from merging main
* fix: add back throwing error if the compactor compacts files persisted by the ingester after the ingester sends max seq_num back to querier
* test: add test_compactor_collision back but modify the input to make it work woth new changes

Fixes#5118.
Given a partition ID, look up the non-deleted Parquet files for that
partition. Separate them into level 0 and level 1, and sort the level 0
files by max sequence number.
This is not called anywhere yet.
`Executor` is only used as a performance boundary, not as a correctness
or data boundary so let's try to re-use it. This also simplifies
profiling of tests since we don't end up with hundreds (or even
thousands) of threads.

* refactor: remove `DecodedParquetFile` from `iox_tests`
* refactor: remove `DecodedParquetFile` from querier
Also pull out all the chunk schema and sort key handling into a function
so that RB chunks and parquet chunks mostly use the same code path.

* fix: use proper sort key in tests
* feat: do not rely on encoded parquet metadata for RB chunks
Ref #4124.
* refactor: allocate less strings
* refactor: use upstream PK calculation
* fix: cache expiration w/o a good reason
* refactor: make namespace cache safer to use
* refactor: make partition cache safer to use
* refactor: `TestPartition::update_sort_key` should return an `Arc`
The whole test framework is built around `Arc`s, so let's fix this
consistency issue.
* fix: actually calculate correct column set in test framework
* feat: check expected parquet file schema
While working on the querier I made some mistakes regarding schemas and
such a check would have greatly improved the debugging experience.
* feat: namespace cache expiration
* fix: improve parquet schema check
* fix: remove clone
* 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!**
Ref #4124.
* refactor: use proper `ColumnSet` type
