RFR: 8283093: JMX connections should default to using an ObjectInputFilter [v4]

[Kevin Walls]

> Set the management.properties  "com.sun.management.jmxremote.serial.filter.pattern" value by default, to restrict types that can be deserialized.
> 
> Use the example value from the Core Libraries guide (see section 2. Serialization Filtering / Built-in Filters / Filters for JMX), plus Subject which is needed when using authentication.
> 
> The sun/management tests run OK with this change.  The existing test sun/management/jmxremote/startstop/JMXStartStopTest.java will fail if the filter specified is made too restrictive.
