### What?
`ResumableJobMixin.get_job_status` had no access to `context`, making it
impossible to handle backends where the remote resource carrying job state can
disappear after completion. I encountered this problem when running Spark with
Kubernetes driver pods which after a run get garbage collected, where without
context an implementation cannot distinguish "SUCCEEDED but pod gone" from
"FAILED but pod gone". The only workaround was `deleteOnTermination=false`,
which accumulates pods indefinitely.
The same gap will also appear in another form in cases when a job is tracked
by external IDs (e.g. EMR `(cluster_id, step_id)`, Glue `(job_name, run_id)`).
### Current behaviour
`get_job_status(self, external_id)` has no context, no access to
`task_store`, no way to cache terminal status before the remote resource
disappears.
### Proposed change
Add `context: Context` as a second parameter to `get_job_status` throughout
the interface.
