* fix: nocache feature code rot
The MBChunk::snapshot code when using the "nocache" option no longer
compiles - this commit updates it to match the not(nocache) code.
* build: use updated broken_intra_doc_links name
The broken_intra_doc_links lint was renamed
rustdoc::broken_intra_doc_links
https://doc.rust-lang.org/rustdoc/lints.html
* chore: Update deps (including arrow 5.0.0 --> arrow 5.1.0)
* chore: update all the things
* refactor: Update serving readiness check due to change in Tonic API
* chore: update more deps

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.

$ cargo run -- database get foobar_weather

}
}
]
},
