Remove "api.vagrant" host requirement from vagrant setup

[GUI]

When setting up a vagrant box for local development, we currently assume the host machine can resolve the api.vagrant hostname. This requires explicitly adding that hostname to your computer's /etc/hosts file. Right now this is needed for the HTTPS redirects when accessing the admin, but it would be best to remove this hostname requirement, so editing your global hosts file is not necessary for local development.

As part of the new installation packages, it listens to all hostnames by default. You can explicitly override it to only listen for specific hostnames, but out of the box, it will listen for everything, which should simplify initial setup.
