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.

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.

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: Avoid some allocations by collecting instead of inserting into a vec
* refactor: Encode that adding columns is for one table at a time
* test: Add another test of column limits
* test: Add below/above limit tests for create_or_get_many
* fix: Explicitly DO NOT check column limits when inserting many columns
* feat: Cache the max_columns_per_table on the NamespaceSchema
* feat: Add a function to validate column limits in-memory
* fix: Provide more useful information when over column limits
* fix: Swap types to remove intermediate allocation
* 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
