Refactor Steps and Sidecars to container_validation

[JeromeJu]

Now that we have container_validations, we shall move the Sidecars and Steps validation which are previously under task_validation to this file since they are more tied with container types rather than Task types.

Thanks @professorabhay . I've updated the issue description to be more detailed with links to the changes you might need to make. In general this is to move the validation of struct Step to the file container_validation. No functional changes would be included.
