azure: add flag for static dns label

ahmetb · Misty Stanley-Jones · commit 52261bb99d7e · 2017-10-17T21:36:21.000-07:00
Introducing --azure-dns argument which associates a FQDN to the
created public IP resource for the VM.

e.g. a value like 'foo' will be later used as IP 'foo.westus.azure.cloudapp.net'.

Also modifying `ip` subcommand to operate on FQDN, where possible.
