[FIX] Setup fix

[mukarramali]

Issues 1: While running, vagrant ssh on mac, it couldn't find precise64. After exploring, found out config.vm.box_url was the issue. Solution: Commented out config.vm.box_url. Choosed hashicorp/precise64 as vm box

Issue 2: bootstrap.sh was not able to reach python packages and I was running into python pip error 'Cannot fetch index base URL' as it is trying to hit http url. Solution: With pip install command in bootstrap had to add -i https://pypi.python.org/simple
