Cleared out static parts of config since it was causing issues

The default config was not working for Ubuntu 14.04 (and I presume any system), since it defined the subsystem twice.

Since the sshd_config is built from the pillar file, I've remove all the extraneous parts from the file (most were comments, one line was causing the issue)

I accidentally included another commit in this one, which adds the PasswordAuthentication in the pillar.example file since it is important for any deployment. If I need to break this into another commit, let me know.
