basic django project deployment on virtual machine [#1]

- There is is no easy way to have provision on demand, we're going to use multi virtual machines.
- Advanages: use prod on demand, fast boot for dev.
- One drawback, developers must type "$ vagrant up dev", it's cool if we could make dev as default
virtual machine when "$ vagrant up". However, vagrant documentation says that, it would up all
defined virtual machines.
