* refactor: improve writer buffer consumer interface
The change looks huge but is actually rather simple. To
understand the interface change, let me first explain what we want:
- be able to fetch watermarks for any sequencer
- have streams:
- each streams tracks a sequencer and has an offset state (no read
multiplexing)
- we can seek a stream
- seeking and streaming cannot be done at the same time (that would be
weird and likely leads to many bugs both in write buffer and in the
user code)
- ideally we don't need to create streams of all sequencers but can
choose a subset
Before this change we had one mutable consumer struct where you can get
all streams and watermark functions (this mutable-borrows the consumer)
or you can seek a single stream (this also mutable-borrows the
consumer). This is a bit weird for multiple reasons:
- you cannot seek a single stream without dropping all of them
- the mutable-borrow construct makes it really difficult to pass the
streams into separate threads
- the consumer is boxed (because its mutable) which makes it more
difficult to handle in a large-scale application
What this change does is the following:
- you have an immutable consumer (similar to the producer)
- the consumer offers the following methods:
- get the set of sequencer IDs
- get watermark for any sequencer
- get a stream handler (see next point) for any sequencer
- the stream handler captures the stream state (offset) and provides you
a standard `Stream<_>` interface as well as a seek function.
Mutable-borrows ensure that you cannot use both at the same time.
The stream handler provides you the stream via `handler.stream()`. It
doesn't implement `Stream<_>` itself because the way boxing, dynamic
dispatch work, and pinning interact (i.e. I couldn't get it to work
without the indirection).
As a bonus point (which we don't use however) you can now create
multiple streams for the same sequencer and they all have their own
offset.

This commit adds a --query-pool flag to router2, used to upsert a
catalog record at startup. Auto-created namespaces will reference this
query pool.
This is for testing only and will be removed in a future commit.
- support long-form (instead of relying on positional arguments)
- use same code as everying else

* fix(REPL): Don't buffer lines until a trailing semicolon is found
The repl would silently buffer all lines until a trailing semicolon were found which
resulted in some very confusing error messages as I would input invalid commands followed
by a command I thought were valid, except I'd still get an error due to the previous command being buffered.
This uses rustyline's helper feature to detect incomplete input (no trailing semicolon) and makes
it accept multiline input until the input is completed.
I also included some of rustyline's default hint and highlighting while I was at it.

All features are now covered by rskafka. This also removes the need to
specify a server ID for write buffer consumers. This was only used for
rdkafka since there we needed to specify a consumer group, even though
we did not use any transactions.
* chore: upgrade rskafka + enable snappy support
* test: ensure that rskafka and rdkakfa work together
Before removing rdkafka ensure that:
- rskafka can consume existing messages produced by rdkafka so we do not
need to drain existing topics
- rdkafka can consume new messages produced by rskafka so we can roll
back
I ran the whole `write_buffer` test suite (including the newly added
tests) using Apache Kafka as well as Redpanda.
* test: ensure we handle consumer offset in error case correctly
* docs: explain test setup

This adds the scaffolding for the ingester server to consume data from Kafka. This ingests data in an in memory structure while creating records in the catalog for any partitions that don't yet exist.
I've removed catalog_update.rs in ingester for now. That was mostly a placeholder and will be going in a combination of handler.rs and data.rs on my next PR which will have some primitive lifecycle wired up.
There's one ugly bit here where the DML write is cloned because it's getting borrowed to output spans and metrics. I'll need to follow up with a refactor to make it so that the DML write's tables can be consumed without it gumming up the metrics stuff.
