There may be many reasons for the discrepancy in jemalloc reported allocations total sizes and RSS.
One of them is that our binary doesn't use jmalloc for all the allocations.
Turns out that jemallocator only sets the global rust allocator. Any call to `malloc` will still
go throught the system allocator. Presumably those calls come from linked C code,
but it's also not impossible that not all rust code honours the global allocator (I have no idea, but let's see)
Logs and traces are emitted via one pipeline. For now, it is not
possible to emit both, but it should be possible in a few weeks, as
tokio/tracing/tracing-subscriber is going through some refactoring recently.
All affected flags are well-documented, and I have tested all but the
OTLP output flags.

Rationale
---------
Our CLI needs to be able to accept configuration as JSON and render configuration as JSON.
Protobufs technically have an official JSON encoding rule called 'jsonpb` but prost doesn't
offer native supprot for it.
`prost` allows us to specify arbitrary derive metadata to be added to generated
code. We emit the `serde` derive directives in the two packages that generate prost code
(`generated_types` and `google_types`).
We use the `serde(rename_all = "camelCase")` to approximate `jsonpb`.
We instruct `prost` to use `bytes::Bytes` for some types, hence we must turn on the `serde` feature
on the `bytes` dependency.
We also use json to serialize the output of the `database get` command, to showcase the feature
and get rid of a TODO. In a subsequent PR I'll teach `database create` (and the yet to be done `database update`) to accept an option JSON configuration body so we can configure partitioning, lifecycle, sharding etc rules etc.
Caveats
-------
This is not technically `jsonpb`. Main issues:
1. default values not omitted
2. no special rendering of special types like `google.protobuf.Any`
Future work
-----------
Figure out if we can get fully compliant `jsonpb`, or at least a decent approximation.

Refactors the API method errors.
The user of the API client needs to be able to distinguish between various error
states when an API request fails. The most ergonomic way of exposing this
information is by returning an error enum that is specific to each API method
(or at least the important ones with well defined failure modes) - currently
only the `create_database()` method has significant error states, so this is
the only one with a specific error type in this impl.
This change defines a bunch of API error codes in the API client, adds them to
the IOx API error response body, and maps them in the API client. Due to error
wrapping the error code mapping in the IOx server is less exhaustive than I had
hoped however.
Initialises a new library crate and implements a basic IOx API client.
The API client supports:
- ping
- create database
Care has been taken to abstract away the underlying HTTP client used
(reqwest) and avoid leaking it into the public API (error types is a
common leak!) This makes updating the HTTP client and/or swapping it for
something else a backwards compatible change for end users of the crate.
Outstanding items:
- move shared API types into a sensible location
- discriminate between various IOx error responses
The former doesn't need doing until we publish the crate and will likely
be rather invasive / conlict prone so aiming to merge this PR and then
move things around in a follow-up.
The latter would allow us to expose error conditions to the user such
that they can take actions to remidy the situation / know if the request
can or should be retried / etc. Currently we expose a string error
message when requests fail, requiring string matching and/or passing the
string higher in the stack (and thus punting the problem to the caller).
It would be very nice to have typed errors, but a detail I have left for
later.
