create pipeline

[SKairinos]

Create a pipeline which will look at all the commit authors of a pipeline and validate if they have signed the latest contributor agreement.

• delete the existing pipeline in the contributor service.
• collect the email addresses of all the commit authors of a pull request.
• call the endpoint on the contributor-backend service.
• If any email addresses are returned, raise an error in the pipeline, print the email addresses, and provide a link to the contributor service with a prompt to sign the latest contributor agreement.
• Call the reusable workflow in all the necessary places, including (but not limited to): py package, js package, frontend arguments, backend workflow.
