【support】 add force pushdown prompt in jdbc connector

[lschampion]

sometimes we wanta a complete pushdown for a query in connector for example:
a query like "select tbl1.id ,tbl1.name ,tbl2.desc from connector_v.tbl1 inner join connector_v.tbl2 .... "
this query involved two tables which both from the same connector. and maybe a query is from one table which iscould be pushdown to the connect for the function are all same with the connector in trino.

As i know pull all record from jdbc connector is rather slow, make the query computation in the connector faster than in trino.
