* refactor: use new ingester<>querier wire protocol
Use and document the new and more flexible ingester<>querier wire
protocol.
Note that the ingester does NOT stream the response data yet, but the
internal data structures would allow that. A follow-up change will
adjust the ingester code to stream the data.
Ref #4849.

* feat: extend flight client to accept multiple (changing) schemas
See #4849.
Originally I intended not to use Flight at all for the new
ingester<>querier protocol. However since flight also deals with
dictionary batches and multiple batches and the gRPC protocol that I
would write would look very similar, I will use Flight with a bit more
flexible message types.
The rough idea for the protocol is the following stream:
- for each partition:
1. "none" message with partition metadata
2. for each chunk (can have different schemas under certain
circumstances):
1. "schema" message (resets dictionary state)
2. (optional) dictionary batch messages
3. one or more "record batch" message
The nice thing about it is that the same arrow client works also for the
existing client<>querier protocol since there we just send:
1. "schema" message (no app metadata)
2. (optional) dictionary batch messages
3. zero, one or more "record batch" message (no app metadata)
* refactor: separate high- and low-level flight client
It is very unlikely that a user will use the high-level batch-producing
functionality and the low-level stuff within the same session. So let's
split this into to clients (high-level uses the low-level one
internally) to avoid confusion.
Also add documentation on our protocol handling.

"end-user -> querier" and "querier -> ingester" should use a single
Flight client implementation. The difference is just the request and
response metadata.
This changes our default Flight client to use protobuf instead of JSON
for the ticket format.

* feat: Add a way to run ingester with an in-memory catalog from the CLI
If you set the --catalog-dsn string to "mem", rather than using that as
a Postgres connection URL, create an in-memory catalog.
Planning on using this in tests, so not documenting.
* fix: Set default topic to the same value as SHARED_KAFKA_TOPIC
Namely, both should use an underscore. I don't think there's a way to
directly share these values between a constant and an annotation.
* feat: Add a flight API (handshake only) to ingester
* fix: Create partitions if using file-based write buffer
* fix: Change the server fixture to handle ingester server type
For now, the ingester doesn't implement the deployment API. Not sure if
it should or not.
* feat: Start implementing ingester do_get, namely decoding the query
Skip serialization of the predicate for the moment.
* refactor: Rename ingest protos to ingester to match crate name
* refactor: Rename QueryResults to QueryData
* feat: Move ingester flight client to new querier crate
* fix: Off by one error, different starting indexes in sequencers
* fix: Create new CLI argument to pick the catalog type
* fix: Create a CLI option to set the number of topics to auto-create in the write buffer
* fix: Check the arrow flight service's health to tell that the ingester gRPC is up
* fix: Set postgres as the default catalog type
* fix: Return an error rather than panicking if CLI args aren't right
* feat: Add db_name/namespace to DmlWrite and DmlDelete
This is required for the new ingester to be able to work with the write buffer. The protobuf that gets serialized over Kafka already includes the database name, it just wasn't getting carried through to the marshaled Dml operation.
* fix: database != namespace, propagation through write buffer

IOx is the only consumer of this API so we might just use the serialized
form. Cloud2 uses the HTTP API which supports SQL-like predicates.
Fixes#3192.
