Remove Cheyenne listings from config_pes.xml file

[nusbaume]

Issue Type

Code Clean-up

Issue Description

Currently the cime_config/config_pes.xml file has multiple references to Cheyenne. However, now that Cheyenne has been decommissioned it would help to remove those references/settings from the file.
