Add overrun qos for pm-cpu/pm-gpu

[ndkeen]

Add overrun as an option for submitting jobs via CIME on pm-cpu/pm-gpu.
Currently, jobs can submit to the overrun qos with case.submit -a="-q overrun".
However, without this PR, tests like this will fail:

create_test SMS_D.ne4pg2_oQU480.F2010 --compiler gnu -q overrun

So with this we could change the test script to run in the overrun queue?

[ndkeen]

Yes, as with previous experience using the shared qos, there must be something in CIME that is unhappy when a job requests to use a qos that is not specified in env_batch.xml. It does not give a great error message when that happens, but adding overrun as an option seems to allow it to work. I suppose it's nice that CIME catches a potential problem when job tries to request a non-existent qos, but it makes it less flexible when a center/machine makes a change to add/remove these.

Note: I'm purposefully trying to use the term qos instead of queue as that is what it's called, but we (and others) often use the word queue. That is, there is no such thing as "debug queue", it's the "debug qos".

Even though the tests don't run on pm-cpu, I will merge to master.
