PLT-7563 Docker images

[bwbush]

@zeme-wana, @shlevy, @paluh, basd on our Sept 27 conversation, I created the bash script make-docker-image.sh that does the spago and webpack builds (from inside the nix develop shell) and then creates a Docker image.

The Dockerfile uses sed to edit in the correct MARLOWE_WEB_SERVER_URL just before launching darkhttpd.

Please review to see that this is sufficient for an interim deployment via docker.

Thanks a lot Brian! I will merge this version as it is but if you have some comments Guys please add them here.

@zeme-wana, @shlevy - can we leave it like that or should I introduce some simple config file which should be added to the app dir and overrides default value?

[shlevy]

I think a config file would ultimately be nicer, but this will work for now.

[shlevy]

Do we need a similar way to override the network name? Or is that inferred now?

[paluh]

@shlevy the network is now inferred from the runtime /healthcheck response headers.
