Add the ability to set reservations from Vagrant.

Do you have any advice on how to refactor this so it doesn't cause robocop warnings? The changes I make are tiny, but happen to push several complexity indicators over their limits.

Well we don't have much actually set in .rubocop.yml; the complexity settings are all in .rubocop_todo.yml. It would take some serious refactoring to get the whole project down to RuboCop's defaults, and I agree that your changes here are pretty tiny (and match the style of the changed files).

I think it'd be fine if you just regenerate the todo file and include it in this PR.

Ok, will do!

Finally passing :)

Looks good, thanks @edmcman!
