    Rewriting header panel's exit policy section
    
    This is gonna take some more work. The last release of arm consulted our
    GETCONF ExitPolicy which excluded both the ExitPolicyRejectPrivate prefix and
    default suffix.
    
    We definitely want to condense the default suffix. As for the prefix, that's
    probably just extra noise. We could just snag the GETCONF like arm previously
    did, but I'd rather address this by making it better in Stem...
