Support vagrant-cachier to speed up fresh boot time

[patcon]

The one criticism I've heard of vagrant-vbguest is that it can add about 45 second to every fresh boot, depending on connection. Perhaps by hooking in at the right time, vagrant-cachier could be used to speed this up.

I suspect this might not be possible, given when vagrant-vbguest patches into the build process before folder sharing, but thought I'd toss the idea out there anyhow :)
