  Create a new digital ocean droplet

       mix doex.droplets.create <name> <options>

  The following options with examples are shown below:

      --region              nyc3
      --size                512mb
      --image               ubuntu-14-04-x64
      --ssh_keys            1234,5467
      --backups             # add option to enable
      --ipv6                # add option to enable
      --user_data           # TODO figure out what this should be
      --private_networking  # add option to enable
      --volumes             # TODO figure out what this should be
      --tags                web,uat,temp

  For example

      mix doex.droplets.create mydroplet \

        --region tor1 \

        --tags myt \

        --image ubuntu-14-04-x64 \

        --size 512mb

  If you have a specific config file, `mix help doex.config` then add it as an environment variable

      DOEX_CONFIG=/tmp/my.doex mix doex.droplets.create mydroplet \

        --region tor1 \

        --tags myt \

        --image ubuntu-14-04-x64 \

        --size 512mb
