InternalConnectorRegistry keeps track of connectors. This class should not be used directly, but
only through the JDBC driver specific SocketFactory implementations.
WARNING: This is an internal class. The API is subject to change without notice.
Calls shutdown on the singleton and removes the singleton. After calling shutdownInstance(),
the next call to getInstance() will start a new singleton instance.
