Vagrant 905834

This adds an option to deploy kitsune via Vagrant with Ubuntu 14.04. 

* ./manage.py generatedata does not currently work, not sure why. Was planning on using an anonymized dump of the production database for data.
* Also, this is blocked until the requirements update in #1984 is merged as well.
Yeah... I think we can get away with version mismatches for most things, but Elasticsearch versions get kind of funky. I highly recommend using 0.90.10 explicitly.

Having said that, maybe it doesn't matter. I don't know what the difference between 0.90.10 and 0.90.13 is. But we definitely can't be using a non-0.90.x version.
