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 Co-authored-by: Curt Bushko <cbushko@gmail.com>
