Vagrant - support for virtualisation providers other than just VirtualBox

[yankcrime]

Vagrant has a pluggable architecture which supports the creation of virtual infrastructure using a selection of providers, and this isn't limited to just VirtualBox. Other common providers are VMware (either Fusion or Workstation), Hyper-V, and KVM.

It'd be good if dcos-e2e allowed for users to spin up a DC/OS environment on the virtualisation platform of their choosing, as long as it's supported by Vagrant.

Thanks @yankcrime - I think that this is a very valid request. That said, I have no current plans to do that as we have no internal requirements for that. PR welcome and I'm happy to help 🙏

@adamtheturtle I'll try and find some time to hack on this a little - I use VMware Fusion on my Mac instead of VirtualBox, hence the request!
