Extras

Replace Role Related Models with Generic Role Model

1. Narrowly defined role models including dcim.DeviceRole, dcim.RackRole and ipam.Role are replaced by a generic extras.Role model.
2. If any of your models are using the replaced role models, it is required for you to remove the role field from your model and add either nautobot.extras.models.roles.RoleModelMixin or nautobot.extras.models.roles.RoleRequiredRoleModelMixin to your model class definition. RoleModelMixin adds a nullable role field whereas RoleRequiredRoleModelMixin adds a required role field.
3. Refer to Role Internals to check out how the extras.Role model works in v2.0.

Updates to Job and Job related models

Job Model Changes

See details about the fundamental changes to the Job Model

Job Logging Changes

1. Job logging is now handled by a logger off the Job itself and has a function for each level to send the message (info, warning, debug, etc).
2. JobResult.log no longer accepts a logger arg and app/job authors should transition to using the Job's logger methods instead of directly calling JobResult.log.
3. There is no longer a log_success or log_failure function. Check out the Job logging changes in detail

JobResult Model Changes

JobResult no longer needs a job_id, user, or obj_type passed to it. It now needs a name, task_name, and a worker. Refer to JobResult Database Model Changes for details.
