Vagrant uses NFS but doesn't suggest the NFS package

[Māris Fogels]

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.
