Removes the min/max timestamp fields from the IoxMetadata proto
structure embedded within a Parquet file's metadata.
These values are redundant as they already exist within the Parquet
column statistics, and precluded streaming serialisation as these
removed min/max values were needed before serialising the file.
Remove the redundant row_count from the IoxMetadata structure that is
serialised into the Parquet file.
The reasoning is twofold:
* The Parquet file's native metadata already contains a row count
* Needing to know the number of rows up-front precludes streaming
Implements an upload() method on the ParquetStorage type, consuming a
stream of RecordBatch, serialising the Parquet file, and uploading the
result to object storage. Returns the IOx-specific file metadata.
Currently while the upload() method accepts a stream of RecordBatch, the
actual resulting Parquet file is buffered in memory before uploading to
object store, due to lack of streaming upload functionality in the
ObjectStore abstraction - this isn't the end of the world, as the files
tend to be relatively small with our current usage.
This impl should be easily modified to be fully streaming once streaming
object store puts are implemented:

Changes the code paths that interact with Parquet files in the object
store to reference the ParquetStorage directly (DRY refactor).
This change takes us from a dependency graph of:
┌─────────────────┐
│ │
▼ │
Parquet Consumer │
│ ┌──────────────┐
├────────▶│ParquetStorage│
▼ └──────────────┘
┌──────────────┐
│ ObjectStore │
└──────────────┘

┌────┴────┐

System (etc)
to:
Parquet Consumer

┌──────────────┐
│ParquetStorage│
└──────────────┘

┌──────────────┐
│ ObjectStore │
└──────────────┘

File s3
System (etc)
With the ParquetStorage being solely responsible for managing
interactions with the object store when dealing with Parquet files.
Renames the Storage type so the context is clear in usage (i.e. fn
args), rather than having to rely on knowing the fully-qualified import
path to know what the type stores.

The sort key is optional and currently only produced by `iox_tests`.
Writing it within the ingester/compactor is tracked by #3968. The sort
key is read by the querier (and this will be verified by the query tests
and is required to merge #4103).

When created in the catalog, parquet files should always have compaction
level 0. Updating the compaction level should always happen in the
compactor.
Only the catalog should need to know about the initial compaction level
value.
This has the advantages of:
- Not needing to create fake parquet file IDs or fake deleted_at
values that aren't used by create before insertion
- Not needing too many arguments for create
- Naming the arguments so it's easier to see what value is what
argument, especially in tests
- Easier to reuse arguments or parts of arguments by using copies of
params, which makes it easier to see differences, especially in tests
