Deployment script

We need to deploy the Meteor backend and Vue.js frontend to a single domain, such as example.com. When a user visits "example.com" the Vue.js frontend would render and connect to the Meteor backend on the same server.

We have been using the [Meteor Up](https://meteor-up.com/) project (MUP) for deployment. MUP basically builds a Docker container from a Meteor project source code and deploys it to a pre-configured server (with nginx and MongoDB already installed). MUP can be extended to add [hooks](https://meteor-up.com/docs.html#hooks), [custom Docker options](https://meteor-up.com/docs.html#docker-options), and [nginx reverse proxy config](https://meteor-up.com/docs.html#reverse-proxy), which might be useful for our deployment purposes.

Ideally, deploying the GeriLife client/server code would be as simple as a single command.
