Feature Request: doctl compute domain create <domain> --droplet-name <droplet-name>

Currently I see no way to fetch and store the IP address from a newly created droplet in order to automate the droplet creation and setting up a domain.

My suggestion is this; add the functionality to specify a droplet name when you are setting up a domain.

Instead of only doing `create domain_name --ip-address droplet_ip_address`.
We could specify the droplet name in a similar manner: `create domain_name --droplet-name droplet_name`

That being said, I welcome any suggestion for fetching the IP address in its purest form, so that I may use that to run with `--ip-address` :)
