perhaps add this new functionality to the existing VM.system_properties

The goal of this PR is to add a means of exposing security properties at
runtime to aid the debugging security related issues/misconfigurations etc.
Currently, only initial security properties set at start up can be exposed via
the `InitialSecurityProperty` JFR event.
This patch introduces a new jcmd diagnostic command `VM.properties`, which
enables developers to print either the current system properties or security
properties of a running Java process via command-line arguments (-system or
-security). To avoid clutter within the jcmd command list, the old
`VM.system_properties` command is hidden, but not removed so will not break
existing usages. The implementation of each is shared to reduce duplication.
Kieran Farrell has updated the pull request with a new target base due to a
merge or a rebase. The incremental webrev excludes the unrelated changes
brought in by the merge/rebase. The pull request contains eight additional
commits since the last revision:
- Merge remote-tracking branch 'origin/master' into sec_props2
- static helper method for both jcmd calls
- missing )
- working with single arg
- updates
- update args
- two args -not yet tested
- initial patch
it seems the ability to hide JCMD commands via DCmdFactory, _hidden has been
removed in JDK-8373441, I will search for an alternative method.
