This commit introduces optional connection rebalancing
for TCP listeners, targeted as cases where there are a
small number of long lived connections such as service
mesh HTTP2/gRPC egress.
Part of this change involved tracking connection counts
at the per-listener level, which made it clear that we
have quite a bit of tech debt in some of our interfaces
in this area. I did various cleanups in service of this
change which leave the connection handler / accept path
in a cleaner state.

Description:
Risk Level: Medium (Opt-in required)
Testing: unit test, integration tested.
Docs Changes: TODO(incfly) add an architecture docs.
Release Notes: New feature, implement `Cluster.transport_socket_matches`. Envoy can be configured to use different transport socket configuration to different endpoints based on metadata match.

This patch moves away from the paradigm of sed-style upgrading of every v2
package to v3alpha. Instead, an additional type analysis phase is
performed prior to protoxform by a protoc plugin known as the "type
whisperer".
The type whisperer produces structured type dependency information for
each .proto. The tools/type_whisperer/typedb_gen.py tool then knits
these together to provide an API-wide type dependency graph. This is
then used to determine which types need upgrading (either they have
breaking changes or transitively depend on types with such changes).
Only packages with upgraded types now undergo the v2 -> v3alpha
transition.
The API type database is checked into
source/common/config/api_type_db.pb. This may seem a strange location,
but in the future we will include the type database as a build artifact
for the Envoy binary, as it will be used by the reflection-based version
converter to find the type upgrade path for input proto.
Risk level: Low (the v3alpha protos are not used yet).
Testing: fix_format, manual inspection of diffs, bazel test //test/...,
docs build.

As part of #8082, we want to be able to (1) automatically generate BUILD
files and (2) treat packages as atomic from a "upgrade / do not upgrade"
decision perspective. This is simplified by having our BUILD targets at
package granularity, since this is what the protoxform plugin operates
on.
This PR broadens the package-level treatment that was already introduced
for Go in #8003 to Python and C++. This simplifies BUILD files
significantly and opens the way to automated generation.
There is some technical debt introduced, since all visibility controls
have been removed. This is slated for reintroduction in
https://github.com/envoyproxy/envoy/issues/8491.
As a bonus (useful for BUILD file generation), also removed the
inconsistency in BUILD package target naming for packages in envoy.api.*
and envoy.type.*. E.g. //envoy/api/v2:v2 is now //envoy/api/v2:pkg.
Risk level: Low (but this will break internal builds and require BUILD
fixups to consuming projects).

* [#not-implemented-warn:] was barely used and its purposes are better
served by [#not-implemented-hide:].
* [#proto-status:] was there for an earlier style of versioning, where
APIs were "frozen" or "draft", etc. Now we have semantic versioning
and a regular API clock as per #6271.

Some example regexes were rendered incorrectly on envoyproxy.io. I chose
to try to find all the example regexes and make them literal text. This
way the regexes are syntactically correct both in the raw proto and on
the doc site. Also found an H2 protocol option with a missing paragraph
due to a blank line vs. empty comment line.

This patch establishes a v3alpha baseline API, by doing a simple copy of
v2[alpha] dirs and some sed-style heuristic fixups of BUILD dependencies
and proto package namespaces.
The objective is provide a baseline which we can compare the output from
tooling described in #8083 in later PRs, providing smaller visual diffs.
The core philosophy of the API migration is that every step will be
captured in a script (at least until the last manual steps),
api/migration/v3alpha.sh. This script will capture deterministic
migration steps, allowing v2[alpha] to continue to be updated until we
finalize v3.
There is likely to be significant changes, e.g. in addition to the work
scoped for v3, we might want to reduce the amount of API churn by
referring back to v2 protos where it makes sense. This will be done via
tooling in later PRs.
