CI step should be placed in /steps repository

User benefits

While we do understand that this is breaking changes from existing behavior Steps is still in experimental and we believe that moving to a structure format will allow our users:

1. To easily recognize if they work on a step or a template
2. Will allow users to name step anyway they'd like and not hard code it to step.yml
