Improve hapi framework

[zane-techempower]

This PR covers:

• Improve hapi's organization w.r.t. handlers for each database set up
• Update dependencies to newest version
• Sequelize (mysql, postgres) uses Promises now
• Add Postgres and Redis tests
• Promisified the redis library so now that uses a Promise approach rather than async
• Promisify mongodb handler
• Improve start up time -- server takes about a minute between when the master cluster forks and all the workers are up and ready. I was able to do a slight optimization that dropped the time by a second, but I was not able to determine the cause of the long delay.
• Add band-aid fix of adding sleep 30 to the setup.sh to give more time.

Took a look at travis. The fails are non-hapi related.

Crystal/moonshine, Rust/iron, and Rust/akka-http are all failing because they do not define what Travis considers to be valid test cases:

• Crystal/moonshine only defines a redis test, this is being fixed in Add Redis as valid database #1653
• The two Rust frameworks have the empty string as their database. I will make a fix right now to set this to "None".

Hopefully those two changes will clean up Travis for working tests such as this. Please test manually for confidence and merge.

Man... Travis is letting me down of late - this worked locally; LGTM!
