Major improvements, version 0.1.0

- Remove redis_ from recipe names (cleaner to see, e.g. redis-multi::foo)
- Fix some rubocop and foodcritic complaints
- _find_all.rb becomes public, renamed to find_all.rb
- Added default attribute for sentinel port number
- Ensure chef-solo usage doesn't fatal out
Found two variables reversed
Found one place where I missed the sentinel port (new attribute)
