- Add dockers for envoy, static assets www server, docker-compose
config generator script. We use `network_mode: host` so that the
loopback addresses within the docker resolve to the host.
- Update build script and angular.json so that copmilation outputs go
directly into the static assets docker directory.
- Update README.md
- remove CORS
- the grpc web host should be window.location.origin, ie the envoy
reverse proxy port
