IMPALA-11992: Support setting query options in Hive JDBC's connection URL
Hive JDBC support setting hive configurations in Connection URL's query
part, thus we can map impala's query options to hive configurations to
support setting query options on the hive JDBC client side. But hive
JDBC will add a "set:hiveconf:" prefix to the configuration key when
request OpenSession() thrift API, we should remove the configuration
key prefix in OpenSession() so that we can set valid query options.
Testing:
- update the 'TestHS2::test_open_session_query_options' EE test.
- add a FE test 'testSetQueryOptionsInConnectionURL' to JdbcTest.

> Hive JDBC support setting hive confs in Connection URL:
> {code:java}
> jdbc:hive2://<host1>:<port1>/dbName;sess_var_list?hive_conf_list#hive_var_list
> {code}
> it will add a "set:hiveconf:" prefix to the configuration key when request
> openSession:
> [https://github.com/apache/hive/blob/master/jdbc/src/java/org/apache/hive/jdbc/HiveConnection.java#L1110.]
> But impala will directly map the configuration's key value pair to query
> option, without cut the key's prefix:
> [https://github.com/apache/impala/blob/4.2.0/be/src/service/impala-hs2-server.cc#L365]
> , we can modify this behavior to satisfy hive jdbc's expectation, and then
> support setting query options in hive jdbc's connection URL.
