Node definition wizard

[hdanak]

It would be great if we could define a new node entirely via a wizard on the CLI.

For instance: amoeba node add

will walk me through the process of creating a new node. I can pick a cloud provider (in this case digital ocean or vagrant), it will show me the options in terms of CPU / RAM configuration, ask me if it's a Rails or Node.js or static (nginx) web server, ask me what other packages I might want, etc.

It should be very easy to use, and basically give me options to build a server. Imagine making it easy enough that your mom (or an intern) can use it.
