xds: fix for delta xDS reconnect bug in LDS/CDS (#12174)
When a wildcard xDS type (LDS/CDS/SRDS) reconnects from a delta xDS stream,
prior to envoy `1.19.0` it would populate the `ResourceNamesSubscribe` field
with the full list of currently subscribed items, instead of simply omitting it
to infer that it wanted everything (which is what wildcard mode means).

This upstream issue was filed in envoyproxy/envoy#16063 and fixed in
envoyproxy/envoy#16153 which went out in Envoy `1.19.0` and is fixed in later
versions (later refactored in envoyproxy/envoy#16855).

This PR conditionally forces LDS/CDS to be wildcard-only even when the
connected Envoy requests a non-wildcard subscription, but only does so on
versions prior to `1.19.0`, as we should not need to do this on later versions.

This fixes the failure case as described here: #11833 (comment)

Support Incremental xDS mode (#9855)
This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged.

Union of all commit messages follows to give an overarching summary:

xds: exclusively support incremental xDS when using xDS v3

Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail.
Work around a strange older envoy behavior involving empty CDS responses over incremental xDS.
xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support

Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead.
Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client.
xds: pull out checkStreamACLs method in advance of a later commit

xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings

In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty.

This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10.

xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time

xds: remove deprecated usages of xDS (#9602)
Note that this does NOT upgrade to xDS v3. That will come in a future PR.

Additionally:

- Ignored staticcheck warnings about how github.com/golang/protobuf is deprecated.
- Shuffled some agent/xds imports in advance of a later xDS v3 upgrade.
- Remove support for envoy 1.13.x but don't add in 1.17.x yet. We have to wait until the xDS v3 support is added in a follow-up PR.

Fixes #8425

Daniel Nephin bbf1a116f6 xds: Fix data race
TestEnvoy.Close used e.stream.recvCh == nil to indicate the channel had already
been closed, so that TestEnvoy.Close can be called multiple times. The recvCh
was not protected by a lock, so setting it to nil caused a data race with any
goroutine trying to read from the channel.

Instead set the stream to nil. The stream is guarded by a lock, so it does not race.

This change allows us to test the agent/xds package using -race.
