`jhsdb debugd` supports server name prefix with \
`sun.jvm.hotspot.rmi.serverNamePrefix` system property. It will be used as remote \
name for SA remote object. It is "SARemoteDebugger" by default.

As a result, remote name will be constructed as following:


//host[:port]/<serverNamePrefix>['_'<id>]


However we have no way to set it excepting system property. jhsdb should provide the \
way to set it as a command line option. And also we should add the way to specify the \
prefix when we connect to debug server. I will add it like `--connect \
id@server:1234/prefix`.

I've also filed [CSR for this PR](https://bugs.openjdk.java.net/browse/JDK-8265897). \
Please review it. This PR modifies DisableRegistryTest.java, but it has been \
addressed in ProblemList-zgc.txt now. So this PR does not affect ZGC.
