Vagrant uses NFS but doesn't suggest the NFS package

Vagrant uses NFS to bind directories on the host system to directories in the guest. However, the vagrant package doesn't suggest or recommend the nfs-kernel-server package.

Steps to reproduce:
1. Install a vagrant box and vagrant config file from a third party - preferrably the config is already set up to use NFS (some github projects provide this as a convenience for their project contributors).
2. Run 'vagrant up'
3. Vagrant complains about NFS not being present on the host system.

Workaround:
Run `sudo apt-get install nfs-kernel-server` on the host system.
