The owner endpoint doesn't return ncim_discovery (so EQUIP_INST_ID
is unavailable from that endpoint). Update extractGraniteFields to
pull hostname from CARD_HOSTNAME, ASN from CARD_ASN, CLLI from
CARD_CLLI, serial from CARD_DEVICE_ID, and vendor/model from
CARD_VENDOR_MODEL in the card_flags array.
Assets without EQUIP_INST_ID are not in Granite and should use
the Add operation in the loader sheet instead of Change.
