Add in option to report internal IP (--report_internal_ip).

--report_internal_ip will report the internal IP instead of the external
IP. This is needed when someone is connecting to the AVD GCE instance from
another GCE instance.

Note: I ignored pylint duplicate code errors since common_operations,
create_cuttlefish_action, and create_goldfish_action are so similar. The
create work will refactor out the common code into 1 place so it's safe
to ignore for now.
