acme command

A golang implementation of the acme factory examples from python and Java APIs

The python implementation is in mmv.py in PCP core (https://github.com/performancecopilot/pcp/blob/master/src/python/pcp/mmv.py#L21-L70)

The Java implementation is in examples in parfait core (https://github.com/performancecopilot/parfait/tree/master/examples/acme)

To run the python version of the example that exits do go run examples/acme/main.go

To run the java version of the example that runs forever, simply add a --forever flag go run examples/acme/main.go --forever
