created & last_updated fields missing from some REST API calls

NetBox version

3.1.6-dev

Python version

3.8

Steps to Reproduce

A number of REST API calls are missing created & last_updated fields in their response. No functional impact however for parity across all API calls perhaps it would be useful to have the fields returned consistently.

Examples:
/api/dcim/virtual-chassis/
/api/dcim/cables/
/api/dcim/power-panels/
/api/dcim/rack-reservations/ (Has created but not last_updated)

Expected Behavior

created & last_updated fields are returned for all relevant objects

Observed Behavior

created & last_updated are missing some some objects

Happy to submit a PR for this.

If accepted, presumably this should be in feature not develop branch due to API changes?

Given that it's a bug, and the fix would restore the API's intended functionality, it's fine to handle in the develop branch. (New features or functionality would need to be implemented in feature.)

Thanks for volunteering!
