    Inside the <code>StaticMembershipInterceptor</code> you can add the static members you wish to have.
    The <code>TcpFailureDetector</code> will do a health check on the static members,and also monitor them for crashes
    so they will have the same level of notification mechanism as the members that are automatically discovered.
