Change change detector to a regular field in the WAGED rebalancer instead of static threadlocal. (#543)

* Change change detector to regular field instead of static thread-local.

The rebalance has been modified to be a thread-local object. So there is no need to keep the change detector as thread-local.
This may cause potential problems.
In addition, in order to avoid resource leakage, implement the finalize method of the WagedRebalancer to close all connections.
