In a multi-threaded environment, addNode() and removeNode() will have thread unsafe issues, divides the existing addNode and removeNode functions into smaller, synchronized operations: addVirtualNode() and removeVirtualNode(). In this way, addNode() and removeNode() also can be called in parallel. And add the ConsistentHash class Unit testing
