Serve xDS resources that embed Armeria custom filter configs

[minwoox]

Motivation:

The xDS control plane parses every stored Listener/Cluster/Route/Endpoint into a proto with a curioswitch MessageMarshaller, which must resolve every google.protobuf.Any it contains (such as an HttpFilter typed_config). The marshaller only registered types under io.envoyproxy.envoy (from java-control-plane) plus a couple of Central Dogma-specific ones. Armeria's xDS filters (e.g. the Athenz access-token filters) are carried as typed_config Any values whose types live in com.linecorp.armeria.xds.athenz and jp.co.lycorp.ftd.athenz.v1, packaged in armeria-xds-api, which Central Dogma did not depend on.

Modifications:

• Make armeria-xds-api the single provider of io.envoyproxy.envoy types in the :xds module.

Result:

• xDS resources that embed Armeria custom filter configs, such as the Athenz access-token filters, can now be created, stored and served by the control plane.

📝 Walkthrough

Walkthrough

The Armeria dependency advances to 1.41.0. The xDS module adds Armeria protobuf types, generalizes protobuf scanning, and adds Athenz typed-configuration parsing and LDS integration tests.

Changes

xDS Athenz support

Layer / File(s)	Summary
Dependency wiring and protobuf marshalling dependencies.toml, xds/build.gradle, xds/src/main/java/.../XdsResourceManager.java	The xDS module adds armeria-xds-api, adjusts transitive dependency exclusions, and scans configured custom protobuf packages for supported message types.
Typed configuration parsing xds/src/test/java/.../XdsTestUtil.java, xds/src/test/java/.../XdsAthenzResourceParseTest.java	Test fixtures place statPrefix in HttpConnectionManager. Tests verify Athenz typed-configuration YAML round-tripping and field unpacking.
LDS listener integration xds/src/test/java/.../XdsListenerServiceTest.java	Integration coverage creates an Athenz-configured listener through HTTP and verifies resource naming, serialization, and LDS discovery.
