This will hold the deterministic ID for partitions.
Until all existing partitions have this value, this is optional/nullable.
The row ID still exists and is used as the main foreign key in the
parquet_file and skipped_compaction tables.
The hash_id has a unique index so that we can look up records based on
it (if it's available).
If the parquet file record has a partition_hash_id value, use that to
generate the object storage path instead of the partition_id.
This commit fixes loads of crates (47!) had unused dependencies, or
mis-configured dependencies (test deps as normal deps).
I added the "unused_crate_dependencies" to all crates to help prevent
this mess from growing again!

This has the minor downside of false-positives when specifying
dev-dependencies for test/bench binaries - these are files in /test or
/benches (not normal tests). This commit includes a workaround,
importing them in lib.rs (gated by a feature flag). I think the
trade-off of better dependency management is worth it!
Still insert them into the database and associate them with namespaces,
but don't ever query them back out.

This commit adds initial support for "soft" namespace deletion, where
the actual records & data remain, but are no longer queryable /
writeable.
Soft deletion is eventually consistent - users can expect to continue
writing to and reading from a bucket after issuing a soft delete call,
until the various components either restart, or have their caches
flushed.
The components treat soft-deleted namespaces differently:
* router: ignore soft deleted namespaces
* ingester: accept soft deleted namespaces
* compactor: accept soft deleted namespaces
* querier: ignore soft deleted namespaces
* various gRPC services: ignore soft deleted namespaces
This ensures that the ingester & compactor do not see rows "vanishing"
from the database, and continue to make forward progress.
Writes for the deleted namespace that are buffered in the ingester will
be persisted as normal, allowing us to support "un-delete" operations
where the system is restored to a the state at which the delete was
issued (rather than loosing the buffered data).
Follow-on work is required to ensure GC drops the orphaned parquet files
after the configured GC time, and optimisations such as not compacting
parquet from soft-deleted namespaces seems like a trivial win.

changed io_shared to iox-shared in the following files: update_catalog.rs, partition.rs, lib.rs (in the service_grpc_catalog folder) and lib.rs (in the service_grpc_object_store folder).
* 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

* 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
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
* chore: Update iox_catalog/migrations/20220607102200_change_sort_key_type_to_array.sql
* fix: Rename migration so it will be applied after
