As per discussion summarized in
#13555 (comment), we will not use structured
xdstp:// names/locators in the API initially. Instead, we will re-use existing string fields for
names and special case any name with a xdstp: prefix. We leave open the option of introducing
structured representation, in particular for efficiency wins, at a later point.

This is a follow up to 2c60632.
This forces all callers to think about multiple header values. There may be places that we want
to support multiple values, but none of them are security critical and this change should be
functionally equivalent to what exists today.

Currently, the maglev hash algorithm default to table size to 65537.
It is the recommended size by a paper but it is better if the user
can set this value.
This patch introduces a new MaglevLbConfig that contains table
size of maglev.
So, now, the user can set the table size of maglev by their situation.

This can be used in similar situations to maglev/ring, but can be used when the host selection must remain the same for existing sessions even if more hosts are added to the cluster.
In a test with 1500 endpoints, updating 50 (remove 50, add 50 different ones) took:
without new setting: ~500ms
with new setting (this PR): ~4ms

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.

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)

This PR introduces a parallel v3 API reference documentation tree to the
existing v2 one.
The docs/root/api-v3/ tree was copied from docs/root/api-v2 and the
necessary package path fixups were made manually. As a result, the tree
largely resembles the v2 docs. Long term this is likely to evolve to
reflect the shape of the new extensions tree.
The message type, field and enum anchors are sed'ed to be distinct and
self-consistent inside api-v3/.
There were a number of API proto changes that were made to obtain a
successful Sphinx build:
* References to deprecated fields were replaced by references to the replacement field.
* clang-format line wrapping in protoxform was removed, this breaks RST in some v3 protos.
* Some packages (type/metadata/v2, data/cluster/v2alpha) were force upgraded to v3, to deal with references to types that are distinct in v2/v3. This is OK as these packages probably make sense to bump for v3, in general we're going to have to think about how to do this more
cleanly, supporting dual v2/v3 references alongside each other.
* Some evil hacks for field renaming added to migrate.py for RouteAction.
There's also some additional machinery added to compute distinct v3/v3
build targets to point protodoc at.
Risk level: Low
Testing: Docs build, manual inspection.

In which we convert every v3alpha reference to v3. In future revs of the
