IMPALA-12642: Support query options for Impala external JDBC table
This patch uses JDBC connection string to apply query options to the
Impala server by setting the properties in "jdbc.properties" when
creating JDBC external DataSource table.
jdbc.properties are specified as comma-delimited key=value string, like
"MEM_LIMIT=1000000000, ENABLED_RUNTIME_FILTER_TYPES=\"BLOOM,MIN_MAX\"".
Fixed Impala to allow value of ENABLED_RUNTIME_FILTER_TYPES to have
double quotes in the beginning and ending of string.
jdbc.properties can be used for other databases like Postgres and MySQL
to set additional properties. The test cases will be added in separate
patch.
Testing:
- Added end-to-end tests for setting query options on Impala JDBC
tables.
- Passed core tests.
