Move to use "get_password" instead of "{user,service,db}_password"

The user_password, service_password and db_password functions are redundant
since they simply call "secret". Creates a get_password function that
will accept a "type" of db, service or user.

All instances of these calls have been changed to call get_password.

Interim commit that keeps the service,db and user functions in order to
merge other changes.

Merge "Rubocop support for recipes."
Remove user_password, db_password and service_password

All cookbooks are using "get_password" now, so removing the redundant
functions as a "clean-up"
