Dynamo unreachable

Working on Windows 10 I am unable to browse content of database with `http://127.0.0.1:3000/orders` endpoint due to docker-related networking issues. This is due to endpoints being defined with hostname `docker.for.windows.localhost` which is no longer domain name used by docker during Docker for Windows installation. Recommended is to use `host.docker.internal`. This change fixes the issue and provides excellent out-of-the-box experience for fresh install of docker for windows.
