RFE: record VM and JMH version into the JSON results, maybe add Runtime.getRuntime().availableProcessors()

[Bernd Eckenfels]

The number of CPUs returned take into account the CPU mask under Windows and for other OS see for example: https://bugs.openjdk.java.net/browse/JDK-6515172

Can you give some pointers?

The only thing that bothers me is that it needs to be repeated per result
since the top level structure is an array. If it happens and the format will
be reconsidered hopefully it gets a struct containing version and results....
