RFR: JDK-8295756 Improve NonLocalRegistry Manual Test Process [v5]

[Bill Huang]

> The current non local registry tests require a manual process that runs rmiregitrty on a different machine and changes the -Dregistry.host property in the source before running the tests on the local machine. This task is created to improve this manual process and provide a clearer instruction to the test engineer about the test requirement. 
> 
> Tests include: 
> java/rmi/registry/nonLocalRegistry/NonLocalSkeletonTest.java 
> java/rmi/registry/nonLocalRegistry/NonLocalRegistryTest.java 
> javax/management/remote/nonLocalAccess/NonLocalJMXRemoteTest.java
