Added vagrant-aspen playbook and vagrant conf

@jarv, can you review this? I'm in the process of testing, to be sure that this works the way I expect. (I mostly copied the vagrant file from `vagrant-fullstack.yml`.)
I talked to @hkim823 and the reason for this to be super verbose was to make it easier to debug when building the base boxes for a release.  I think `vvvv` was too much but `vvv` is probably good for the base full stack file.
