* Add Tproxy support to Envoy Extensions (this is needed for service to service validation)
* Add validation for Envoy configuration for an upstream service
* Use both /config_dump and /cluster to validate Envoy configuration
This is because of a bug in Envoy where the EndpointsConfigDump does not
include a cluster_name, making it impossible to match an endpoint to
verify it exists.
This removes endpoints support for builtin extensions since only the
validate plugin was using it, and it is no longer used. It also removes
test cases for endpoint validation. Endpoints validation now only occurs
in the top level test from config_dump and clusters json files.

* Protobuf Modernization
Remove direct usage of golang/protobuf in favor of google.golang.org/protobuf
Marshallers (protobuf and json) needed some changes to account for different APIs.
Moved to using the google.golang.org/protobuf/types/known/* for the well known types including replacing some custom Struct manipulation with whats available in the structpb well known type package.
This also updates our devtools script to install protoc-gen-go from the right location so that files it generates conform to the correct interfaces.
* Fix go-mod-tidy make target to work on all modules
This gets the extensions information for the local service into the snapshot and ExtensionConfigurations for a proxy. It grabs the extensions from config entries and puts them in structs.NodeService.Proxy field, which already is copied into the config snapshot.
Also:
* add EnvoyExtensions to api.AgentService so that it matches structs.NodeService
* extensions: refactor PluginConfiguration into a more generic type
ExtensionConfiguration
Also:
* adds endpoints configuration to lambda golden tests
* uses string constant for builtin/aws/lambda
