Fixes
- Hardcode Envoy's reloadable feature for TE header sanitization to false. This feature as it exists in 1.29.2 breaks gRPC upstreams whose client library expects
TE: trailers. This hardcode will be removed when Gloo Edge depends upon 1.29.3, which has a fix for the gRPC case but is currently unreleased. (#9232) - The Gloo Gateway deployer now gets the xDS host and port from the gloo service, instead of using potentially incorrect values. (https://github.com/solo-io/solo-projects/issues/5949)
