HBASE-24805 HBaseTestingUtility.getConnection should be threadsafe
* refactor how we use connection and async connection to rely on their access methods
* refactor initialization and cleanup of the shared connection
* incompatibly change HCTU's Configuration member variable to be final so it can be safely accessed from multiple threads.
