Pass default domain to remote drush command

[rmott-littler]

Motivation
As a manager of a dozen applications at Acquia, I want to use acli remote:drush to perform routine tasks (especially uli login) on multiple remote applications without remembering to type the correct --uri every time. Previously with Drupal 7/drush 8/Acquia Cloud API v1 one could use drush acquia-update to easily keep local aliases up-to-date, but this is no longer an option.

Proposed changes
Since remote:drush is already fetching the Acquia environment information behind the scenes for the alias provided, it should pass along the default_domain parameter when none is given by the user. Allow the user to continue to provide their own --uri parameter if the default isn't sufficient (on a drush command, the last duplicate parameter wins).

Alternatives considered
Manually typing the correct --uri flag when needed for a drush command like uli is redundant and painful.

Testing steps/example usage
acli remote:drush site.dev -- status --fields=uri

Before: http://default
After: http://sitedev.prod.acquia-sites.com

acli remote:drush site.dev -- uli

Before: http://default/user/reset/1/.../login
After: http://sitedev.prod.acquia-sites.com/user/reset/1/.../login

acli remote:drush site.dev -- uli --uri=https://example.com

Before: https://example.com/user/reset/1/.../login
After: https://example.com/user/reset/1/.../login (no change; the user override was unaffected)
