Adds support for default ClientInfo properties. These are not required by the JDBC standard, but many applications (including IntelliJ) will try to set these, and will log a warning if they are not set. This will prevent that warning from being logged.

As a next step, these ClientInfo property values should be set as SessionLabel values in Cloud Spanner. This makes it possible to track which sessions are being used by which (JDBC) application.
