Ensure nothing in the troubleshoot go module depends on consul's top level module. This is so we can import troubleshoot into consul-k8s and not import all of consul.
* turns troubleshoot into a go module [authored by @curtbushko]
* gets the envoy protos into the troubleshoot module [authored by @curtbushko]
* adds a new go module `envoyextensions` which has xdscommon and extensioncommon folders that both the xds package and the troubleshoot package can import
* adds testing and linting for the new go modules
* moves the unit tests in `troubleshoot/validateupstream` that depend on proxycfg/xds into the xds package, with a comment describing why those tests cannot be in the troubleshoot package
* fixes all the imports everywhere as a result of these changes

This commit adds the xDS resources needed for INBOUND traffic from peer
clusters:
- 1 filter chain for all inbound peering requests.
- 1 cluster for all inbound peering requests.
- 1 endpoint per voting server with the gRPC TLS port configured.
There is one filter chain and cluster because unlike with WAN
federation, peer clusters will not attempt to dial individual servers.
Peer clusters will only dial the local mesh gateway addresses.
* add golden files
* add support to http in tgateway egress destination
* fix slice sorting to include both address and port when using server_names
* fix listener loop for http destination
* fix routes to generate a route per port and a virtualhost per port-address combination
* sort virtual hosts list to have a stable order
* extract redundant serviceNode
Peered upstreams has a separate loop in xds from discovery chain upstreams. This PR adds similar but slightly modified code to add filters for peered upstream listeners, clusters, and endpoints in the case of transparent proxy.
