Merge pull request #3004 from bertinia/maint-5.6_archive_metadata

update for stand-alone CMIP6 query outside of a caseroot
update to archive_metadata stand-alone functionality so that a Case object is not incorrectly instantiated when the --query_cmip6 command line option is called outside of a caseroot.
