Verify that the selected queue type can be used

Describe the bug

Bad traceback in case the cluster runner is ill configured. It would be nice if ert could check that the selected driver can be used before trying to submit jobs.

To reproduce Steps to reproduce the behaviour:

1. Connect to equinor azure node
2. ert gui my_config.ert
3. Run experiment (IES/Smoother/ESMDA/Test)
4. …

Expected behaviour A better error message

Screenshots The following will be printed in terminal the amount of times we send qsub (so at least once for each realisation)

Environment

• ERT/Komodo release: Any
• Remote/HPC execution involved: yes

Additional context The reason is that the default pbs server cannot be used, and it is expected that the user sets the server themselves.

$ cat /etc/pbs.conf
PBS_EXEC=/opt/pbs
PBS_SERVER=Please set SERVER_NAME in your environment
