Use jcmd to generate dumps for openj9 hangs

Fixes #103

[lumpfish]

This PR does the following:

1. Creates a getJavaProperties method to return the properties listed by java -XshowSettings:properties as a hash array
2. Creates a java_properties_check.pl script which can be used to test the getJavaProperties method from the command line.
3. Uses the getJavaProperties method to determine whether java.vm,name contains J9. If it does, and and there is a jcmd.exe executable in the jdk bin directory, jcmd is called to take the dumps rather than procdump.exe.

Output from a test run of the PR running the stf SampleOverrunTest:

Could we fix this typo? "propertiesfor" -> "properties for".

[Mesbah-Alam]

LGTM. Approving assuming the typo will be fixed.
