Issue:

1. Creating this PR to add a new attribute called device_type to the scheduler model
2. I am not adding this to the schedule "build" logic as this has to be inferred from the device_make that is inside the job_data in json format.
3. This is the PR that is dependent on this change - https://github.extremenetworks.com/Engineering/GoDCApp/pull/25470
