Allow adding custom Domains to environments.

[jonpugh]

• Modify Config.php to turn Domains into an array or list: https://github.com/terra-ops/terra-cli/blob/master/src/terra/Config.php#L82
• Add a command class terra\Command\Environment\EnvironmentDomains: "environment:domains".
• Add the command class to terra\Console\Application::getDefaultCommands()
• Add all the Domains to terra\Factory\EnvironmentFactory::getDockerComposeArray()

I've updated the issue with the new plan:

New commands:

terra environment:domains - List all domains attached to an environment.
terra environment:domains add - Add a domain to an environment.
terra environment:domains remove - Remove a domain from an environment.

Ok, this seems to work!!

I'd like to add more features in the future like DNS checks, but I think it's working well enough to close the issue.

@jlyon: Check it out and let me know what you think!!

Awesome! I'll take a look today

This works great for me after I added domains: {} to each environment in ~/.terra/terra. This is really awesome. Nice work!

Note for others, "add" comes after app and environment in the command:

terra  environment:domains [<app_name>] [<environment_name>] [<action>] [<domain>]

so:

terra  environment:domains drupal dev add dev-drupal.example.com
