Originally BaseJob ORM model was extended and Polymorphism has been used to tie different execution logic to different job types. This has proven to be difficult to handle during AIP-44 implementation (internal API) because LocalTaskJob, DagProcessorJob and TriggererJob are all going to not use the ORM BaseJob model, but they should use BaseJobPydantic instead. In order to make it possible, we introduce a new type of object BaseJobRunner and make BaseJob use the runners instead. This way, the BaseJobRunners are used for the logic of each of the job, where single, non-polimorphic BaseJob is used to keep the records in the database - as a follow up it will allow to completely decouple the job database operations and move it to internal_api component when db-lesss mode is enabled. <!-- Thank you for contributing!
