Add ASCII logo, banner on startup in development mode Resolves #1520

1. Banners in `Sidekiq::Banners`
2. Check if we are in `development`
3. Check `Sidekiq::NAME` and print appropriate banner.

To avoid cluttering the `print_oss_banner` method with escaping color codes, I opted to just wrap the
method with the red and reset codes. Hope this is what you were looking for! I :heart: Sidekiq!
