IMPALA-11054: Support resource pool polling for frontend
To support different sizes of resource pools, Planner will need to poll
resource pool which is only done by backend currently.
This patch splits the Java class RequestPoolService as two classes -
JniRequestPoolService and RequestPoolService, makes RequestPoolService
as singleton class and provides an API for frontend to access
RequestPoolService instance.
Testing:
- Manually verified that Planner could access RequestPoolService
instance with RequestPoolService.getInstance().
- Passed core tests.
