Honor strict option when catching data error during CSV load

The Phoenix CSV Bulk Loader has a strict option (i.e. -s or --strict) which is intended to abort the load if a data error is found. Looks like we're not passing this option through the errorOnRecord method, but I think that'd be a good (and likely pretty easy) improvement:

        @Override
        public void errorOnRecord(CSVRecord csvRecord, String errorMessage) {
            LOG.error("Error upserting record {}: {}", csvRecord, errorMessage);
        }
