Add saltstack state definitions

Also includes pillar data. Static stuff goes into salt, dynamic stuff
(like secrets, database urls, bind urls, etc) go into pillar.

Secret data is encrypted using tool added: tools/secure_data.py. Secrets
are encrypted with a secret, travis has a copy of the secret and can use
that to decrypt and deploy stuff. User account for travis and deployment
script will be added later.

The goal is that an environment as close to prod as possible can be set up
locally with only secrets and bind urls different. It's pretty close now,
except from in prod the database is on an external server.

Run `vagrant up` to set up the environment locally. See readme for more
instructions.
