Subject: [PATCH] route-adapter: its step is a run-once process (hq ADR 0198)

The mesh-route-adapter container goes with its Dockerfile and build bases. The step runs node on the bundle as a run-once process, reading what the mesh contributed and its config where the mesh writes them and writing the proxy's dynamic directory at the path the container used to mount; it still runs again when a route or its config changes.
