* Use plain double for active request bias
Use a plain double instead of a runtime double to store the per-cluster
active request bias.
Note: The goal of this commit is to evaluate the memory overhead of this
approach. A commit with te Least Requests LB changes might follow if we
deem the memory overhead of this approach acceptable.

These are currently set as [#not-implemented-hide:]. There should be enough plumbing here to start
implementing the first roadmap steps in #11264, i.e. some simple delta discovery flows with core
LDS/CDS/RDS/EDS/SDS.
I've punted on VHDS and SRDS until later, as these will require special case mapping of their
resource keys into context parameters.
Risk level: Low (Unused API changes).
Testing: Built docs and proto_format.sh.
Part of #11264.

Mainly moving code, but finishes up the series of pluggable upstream PRs.
Additional Description: This unhides the configurable extension point to the cluster for selecting a connection pool and creating an upstream, which can be used for custom business logic in upstream creation.
Risk Level: medium (router refactor)
Testing: with prior PRs
Docs Changes: inline with APIs
Release Notes: added

split out from #11327
There's a bit of transitive ugliness: declaring the extensions requires security posture, requires stub build files, requires codeowners before the code move, but it'll be pretty short lived.
Risk Level: Low (mostly only APIs)
Testing: n/a
Docs Changes: some of the new docs
Release Notes: n/a

Fixes a mismatch in metadata attribute name used by transport_socket_matches
Risk Level: Low
Testing: Manual review
Docs Changes: Not applicable
Fixes#10660

Users can specify metadata in a health check's config that will be
used to select a matching transport socket from those configured in a
cluster's transport_socket_matches. This allows users to configure a
different transport socket for health check connections than the one
that is used to create a connection to an endpoint for proxying.
Risk Level: low; small optional feature
Testing: added unit tests
Docs Changes: updated health check and cluster proto docs with an explanation and example.
Release Notes: added
Fixes#10575

This patch performs a major version freeze and bump by modifying
package_version_status, using the tooling developed in #10636.
Specifically:
v2 APIs are frozen (except for where they are the latest in their
package history and still active)
v3 APIs are transitioned to be active
Candidate v4alpha APIs are generated (not used by Envoy yet)
Fixes#10355
Risk level: medium (entire API's files are modified, visually verified
to ensure things look sane, all tests pass)
Testing: CI
