[TACHYON-127] Deploy Tachyon Cluster through Vagrant 

What's working?
We can start a Tachyon cluster on VirtualBox and AWS using HDFS 2.4.1 and glusterfs as under filesystem.

What next?
- more under filesystem (ceph, hadoop 1.0.4)
- more providers: Docker, OpenStack.

Oh with VPC it works, I misunderstood what you meant by any ip in the region. Thanks for considering my feedback!
