connect: enable proxy.passthrough configuration Enable configuration of HTTP and gRPC endpoints which should be exposed by the Connect sidecar proxy. This changeset is the first "non-magical" pass that lays the groundwork for enabling Consul service checks for tasks running in a network namespace because they are Connect-enabled. The changes here provide for full configuration of the connect { sidecar_service { proxy { expose { paths = [{ path = <exposed endpoint> protocol = <http or grpc> local_path_port = <local endpoint port> listener_port = <inbound mesh port> }, ... ] } } } stanza. Everything from `expose` and below is new, and partially implements the precedent set by Consul: https://www.consul.io/docs/connect/registration/service-registration.html#expose-paths-configuration-reference Combined with a task-group level network port-mapping in the form: port "exposeExample" { to = -1 } it is now possible to "punch a hole" through the network namespace to a specific HTTP or gRPC path, with the anticipated use case of creating Consul checks on Connect enabled services. A future PR may introduce more automagic behavior, where we can do things like 1) auto-fill the 'expose.path.local_path_port' with the default value of the 'service.port' value for task-group level connect-enabled services. 2) automatically generate a port-mapping 3) enable an 'expose.checks' flag which automatically creates exposed endpoints for every compatible consul service check (http/grpc checks on connect enabled services).
