Implementation of informally used Java API to preserve compatibility with older code that uses
CoreSocketFactory.
See Also: com.google.cloud.sql.ConnectorRegistry
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.
