[feat] Skip the test if its associated Slurm job has expired

[vkarak]

If the job's state is DEADLINE, then the associated test is skipped. Here's an example:

Previously, the test was continuing and failed in sanity checking because stdout/stderr were not present:

FAILURE INFO for stream_build_test (run: 1/1)
  * Description:
  * System partition: pseudo-cluster:compute
  * Environment: gnu-mpi
  * Test file: /home/admin/reframe-examples/tutorial/stream/stream_build_run.py
  * Stage directory: /scratch/rfm-stage/stage/pseudo-cluster/compute/gnu-mpi/stream_build_test
  * Node list: None
  * Job type: batch job (id=70)
  * Dependencies (conceptual): []
  * Dependencies (actual): []
  * Maintainers: []
  * Failing phase: sanity
  * Rerun with '-n /6c084d40 -p gnu-mpi --system pseudo-cluster -r'
  * Reason: sanity error: rfm_job.out: No such file or directory
--- rfm_job.out (last 10 lines) ---
--- rfm_job.out (ERROR: [Errno 2] No such file or directory: '/scratch/rfm-stage/stage/pseudo-cluster/compute/gnu-mpi/stream_build_test/rfm_job.out') ---
--- rfm_job.err (last 10 lines) ---
--- rfm_job.err (ERROR: [Errno 2] No such file or directory: '/scratch/rfm-stage/stage/pseudo-cluster/compute/gnu-mpi/stream_build_test/rfm_job.err') ---

Now the test is skipped with an informative message:

[----------] start processing checks
[ RUN      ] stream_build_test /6c084d40 @pseudo-cluster:compute+gnu
[     SKIP ] (1/2) stream_build_test /6c084d40 @pseudo-cluster:compute+gnu [the associated job 71 has expired]
[ RUN      ] stream_build_test /6c084d40 @pseudo-cluster:compute+gnu-mpi
[     SKIP ] (2/2) stream_build_test /6c084d40 @pseudo-cluster:compute+gnu-mpi [the associated job 72 has expired]
[----------] all spawned checks have finished

Closes #3700.
