Comment 2 for bug 1842119

i dont think its a mismatch issue since we have a map function in manila.py
def _map_quota_names_for_update(data):
    mapping = {
        'share_gigabytes': 'gigabytes',
        'share_snapshots': 'snapshots',
        'share_snapshot_gigabytes': 'snapshot_gigabytes',
    }
