Support fetching job data from SLURM's REST API

REST API versions seem to be diverged between `0.0.37` and latest `0.0.41`. Try to support [v0.0.37](https://slurm.schedmd.com/archive/slurm-21.08.5/rest_api.html) and [v0.0.40](https://slurm.schedmd.com/archive/slurm-23.11.0/rest_api.html) that can potentially support other versions too.
