Remove jdk.packager.services.UserJvmOptionsService

After some deliberation we have decided to remove The UserJvmOptionsService from jpackager.
The current implementation is not well thought out, nor does satisfy any pressing need. We may reconsider this in a later release.
As a result of this decision we need to remove:
1.) The main Interface UserJvmOptionsService.java in jdk.packager.services.
2.) The Service implementation in jdk.packager.services.userjvmoptions.
3.) The command line argument "--use-jvm-args"
4.) support code for implementation of any of the aboive.
