Tiewei Fang 3e8b3d68fc [BugFix](jdbc catalog) fix OOM when jdbc catalog querys large data from doris #18067
When using JDBC Catalog to query the Doris data, because Doris does not provide the cursor reading method (that is, fetchBatchSize is invalid), Doris will send the data to the client at one time, resulting in client OOM.

The MySQL protocol provides a stream reading method. Doris can use this method to avoid OOM. The requirements of using the stream method are setting fetchbatchsize =  Integer.MIN_VALUE and setting ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY
