Heroku Release Phase + Review Apps + Rails

This is a simplified, but fairly thorough, set of scripts and configuration to enable Heroku Release Phase for Rails apps. Further, this particular set up plays nicely with Heroku Review Apps in that the release phase script will:

Fail, loudly, if the DB does not yet exist.
Load the DB schema if the current schema version (as determined by bin/rails db:version) is 0.
Run DB migrations otherwise.

For a "normal" app that usually means it will run the DB migrations.

	def fizz_buzz(number)
	r = case {r3: number % 3, r5: number % 5, number:}
	in { r3: 0, r5: 0} then "FizzBuzz"
	in { r3: 0} then "Fizz"
	in { r5: 0} then "Buzz"
	else number
	end
	puts r
	end
