closes #7

Overview

This pull request introduces a series of new protobuf objects designed to support the integration of Argo as part of our work on improving the scheduled API. The additions comprehensively support basic Create, Read, Update, and Delete (CRUD) operations with an additional extension for List, which Naas's respective APIs will later consume.

Custom Resource Definitions (CRDs) for the essential resources needed for scheduling workflows on Argo were also added to help with the validation process in the backend. These changes are modeled after the resources outlined in this base Example Workflow provided by Argo, and aim to support its variations with an emphasis on DAG workflow runs.

Main Additions

The PR incorporates several vital components integral to the workflow, as listed below:

• Metadata: Enhancing data descriptors to support better categorization and identification within the Argo workflow and our organization logic, later to be used as a filtering mechanism of user_id, creation_date, etc.
• Spec: Detailed specifications for the workflow;
• Entrypoint: Defining the initial step or action in the workflow;
• Templates: standard workflow components, ensuring consistency and efficiency;
• Dag: complex task dependencies workflows;
• Script: Enabling the embedding of scripts within the workflow;
• Inputs/Outputs: Defining the expected inputs and outputs gives us the ability to use S3 stores for artifact recovery;
