Include COMPRESSS_ARCHIVE_FILES option for NorESM3

[TomasTorsvik]

For noresm2 we had the option to automatically compress output files to netcdf4 format when moving output files into the archive directory. Would it be possible to include this option for noresm3?

From: cime/scripts/lib/CIME/case/case_st_archive.py:

    if self.get_value('COMPRESS_ARCHIVE_FILES'):
        archiveroot = self.get_value('DOUT_S_ROOT')
        convert='/noresm2netcdf4.sh'
        cmd_convert=caseroot+convert
        cmd="%s %s" %(cmd_convert,archiveroot)
        logger.info("cmd={}".format(cmd))
        run_cmd_no_fail(cmd)
