This patch introduces a new tool, protoxform, that will be the basis of
the v2 -> v3 migration tooling. It operates as a Python protoc plugin,
within the same framework as protodoc, and provides the ability to
operate on protoc AST input and generate proto output.
As a first step, the tool is applied reflexively on v2, and functions as
a formatting tool. In later patches, this will be added to
check_format/fix_format scripts and CI.
Part of #8082.
Risk level: medium (it's possible that some inadvertent wire changes
occur, if they do, this patch should be rolled back).
Testing: manual inspection of diff, bazel test //test/..., some
grep/diff scripts to ensure we haven't lost any comments.

This is a MVP for the HTTP tap filter. It includes minimal
infrastructure for the following:
1. Generic tap configuration which in the future will be used for
static config, XDS config, etc. In this MVP the tap can be
configured via a /tap admin endpoint.
2. Generic output configuration which in the future will be used for
different output sinks such as files, gRPC API, etc. In this MVP
the tap results are streamed back out the /tap admin endpoint.
3. Matching infrastructure. In this MVP only matching on request and
response headers are implemented. Both logical AND and logical OR
matches are possible.
4. In this MVP request/response body is not considered at all.
5. All docs are included and with all the caveats the filter is ready
to use for the limited cases it supports (which are likely still to
be useful).
There is a lot of follow on work which I will do in subsequent PRs.
This includes:
1. Merging the existing capture transport socket into this framework.
2. Implementing body support, both for matching on body contents as
well as outputting body data.
3. Tap rate limiting so too many streams do not get tapped.
4. gRPC matching. Using reflection and loaded proto definitions, it will
be possible to match on gRPC fields.
5. JSON matching. If the body parses as JSON, we can allow matching on
JSON fields.
