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.
All our catalog tests run as one test, over one database connection.
Prior to this commit, there was no state reset during test execution, so
earlier tests would pollute the state of later tests, making it an
increasingly complex and intermingled set of tests trying to assert
their entities while ignoring other, previously created entities (or
changing the order of test execution in search of the golden ordering
that makes everything great again.)
This is a bit of a hack, and is not how I'd have structured catalog
testing w/ clean state if I was writing it fresh. It is what it is.
This has been driving me mad for SO LONG it's SO BAD <shakes fist>.

The maximum number of tables is part of the Namespace, which is already
loaded in its entirety. This commit copies the value into the
NamespaceSchema, making it available for the router to utilise.
We use UTC, but that doesn't mean everyone does. Queries that utilise
NOW() will return incorrect results when the server is using a non-UTC
tz, but application-provided UTC timestamps / epochs.

Updating the sort key is not commutative and MUST be serialised. The
correctness of the current catalog interface relies on the caller
serialising updates globally, something it cannot reasonably assert in a
distributed system.
This change of the catalog interface pushes this responsibility to the
catalog itself where it can be effectively enforced, and allows a caller
to detect parallel updates to the sort key.
To avoid other tests' state bleeding into this one and this one's state
bleeding into other tests, now that it's testing some queries without
scoping by shard.

The checks for whether a column already exists with a different type
were relying on ordering of the input matching the ordering of the
columns returned from inserting the columns in Postgres.
Rather than trying to match the new ordering that is required to avoid
Postgres deadlocks, switch from a Vec to a HashMap and look up the
column type from the name.
This also reduces some allocations that weren't really needed.

* fix: Provide more useful information when over column limits

* docs: Explain the interactions of the cache and the column limits
* test: Actually set up test that showcases column limit race condition
* fix: Allow writing to existing columns even if table is over column limit

This commit removes tombstone support from the ingester, and deletes
associated code/helpers/tests. This commit does NOT remove tombstone
support from any other service, but MAY include removing overlapping
test coverage.
This also removes the tombstone support from the Ingester -> Querier RPC
response message.
This has the nice side effect of removing a whole lot of thread spawning
in the ingester tests for the Executor, speeding everything up!
This commit carries the SortKey in the PartitionData, and configures the
ingester to use deferred sort key lookups, smearing the lookups across a
fixed period of time after initialising the PartitionData, instead of
querying for the sort key at persist time.
This allows large numbers of PartitionData to be initialised without
causing a equally large spike in catalog load to resolve the sort key -
instead this load is spread out randomly to reduce peak query rps.

Adds a Partition::most_recent_n() method to the catalog interface,
returning the N most recent partitions for a given set of shards.
The most recently created partitions are likely to be currently "hot"
for writes, and are cheap to list.

* fix: Remove some needless borrows, thanks clippy

The default statement logging verbosity of the `sqlx` crate is INFO, which
is frankly surprising.
The reason we didn't bother with lowering this before is that the `sqlx` crate
emits logs using the `log` crate, and we're using the `tracing` crate for logging too.
We did bridge the two logging ecosystems with https://docs.rs/tracing-log/latest/tracing_log/
but until https://github.com/influxdata/influxdb_iox/pull/5680 the bridge wasn't really working
so we didn't notice the *very* verbose logs of sqlx sstatement logging (which log our whole SQL multiline statements as INFO logs...)
Adds a migration to add a column "persisted_sequence_number" that
defines the inclusive upper-bound on sequencer writes materialised and
uploaded to object store for the partition.
