Test external database

[ehelms]

This is using Vagrant to provide a way to do external database testing. There is a command dedicated to setting up an external database in the development CLI. I am starting with a separate job focused on just testing the external database.

I updated this for now to be based off the other prototype (#143) that includes development CLI, that allows building in this deployment, e.g.

./forge vms start --vms database
./forge remote-database

Where the last command will configure a database host to be external for development and testing. This starts to feel like what Forklift could also be, or Forklift could evolve into this repo or a mix of the two.

This is passing now! This includes a commit that re-works how the test command generates the ssh-config to base it off the Ansible inventory instead of Vagrant. This addresses the error that Vagrant throws if not all boxes are provisioned when requesting ssh-config and makes the test command able to work with more environments.

Added documentation

This includes #326 since the database checks fail for foreman-proxy setup (which doesn't require a database).

I split out one of the commits as it would be useful beyond this -- #346
