Title: Modify REDISTOGO_URL parameters

I made three related changes:

1. Allowed the ability to use REDIS_URL as well as REDISTOGO_URL environment variable to set redis params.
2. Added better parsing functionality for password in the Redis URL
3. Switched from Optimist to Yargs, since Optimist is deprecated and suggests going to Yargs.
