RFR: JDK-8187498: Add a -Xmanagement flag as syntactic sugar for -Dcom.sun.management.jmxremote.* properties

[Harsha Wardhana B]

Hi Erik,

The minimal command line would be,

"-Xmanagement", that will start only the local management server.

"-Xmanagement:local=true,port=aaaa" will start the remote management 
server without SSL or authentication.

If we use property, that doesn't exist, we get invalid option error. As 
said before, no options are mandatory.
/<log>//
//./java -Xmanagement:ssl=true,authenticate=false,rmiregistry_ssl=true 
HelloWorld//
//Error: Invalid option specified: rmiregistry_ssl//
