added a vagrant config for the dev app server and a section for the digital ocean provider.
Using the digital ocean provider requires a separate file `secrets.rb` ex:

```
module MyVars
  TOKEN = ""
end
```

The digital ocean vps can be provisioned by running

```
vagrant up devapp --provider=digital_ocean
```
