com.sun.ts.lib.harness.RemoteStatus should have an exception

[starksm64]

Is your feature request related to a problem? Please describe.
The com.sun.ts.lib.harness.RemoteStatus type should have a Throwable field for any exception that is thrown during the test.

Describe the solution you'd like
The legacy handling of server side exceptions was based on the TestUtil class and a remote logging feature. The modern way would be to have the returned status object contain the error information for use in the client side test framework.

Additional context
The current 11.0.0 implicit serialVersionUID of the com.sun.ts.lib.harness.RemoteStatus is:
