Virtual Box Providers that flix-tech/vagrant-kubernetest support

[gargnupur]

Hello,

We are trying to test this with providers other than virtual box and tried kvm and libvirt but get following error:
default: Box Provider: libvirt
default: Box Version: >= 0
==> default: Loading metadata for box 'flixtech/kubernetes'
default: URL: https://vagrantcloud.com/flixtech/kubernetes
The box you're attempting to add doesn't support the provider

What all providers does this box support?

Right now this box only supports the virtualbox provider. Also quite some parts in the Makefile are virtualbox specific so there would be a bit of effort to port. Also it's important that the provider supports private networking for the service forwarding and mdns discovery to work.

Also there's now an ansible branch that allows configuring the network dynamically for the machine, which also should make it easier to port it to other providers. Though I don't have plans for that. I'm open for pull requests though.
