Title: Allow externally-defined data_sources.json, and allow empty password.

These were the minimal changes necessary to allow me to run the datasource tests. This pull request allows the user to configure their data sources JSON file by setting a `DATASOURCES` environment variable. There'd be a couple other ways to do this, but this was the simplest for now and is consistent with datazilla, which also handles config via env vars.

I also made the "passwd" key optional, since locally my user can connect to MySQL without a password.
