GEODE-6033: Add VMEventListener for DUnit Rules (#3161)

A DUnit Rule (or even a test) can now register a VMEventListener:

VM.getVMEventListenerRegistry().addVMEventListener(vmEventListener);

VMEventListeners will receive the following notifications:

void afterCreateVM(VM vm);
void beforeBounceVM(VM vm);
void afterBounceVM(VM vm);

DUnit Rules can use these callbacks in order to support dynamic 
creation or bouncing of VMs.

Add junitparams dependency to geode-dunit.

> I just noticed that if you try to use SharedErrorCollector in a DistributedTest that uses vm.bounce, the after() in the Rule will throw NullPointerException in the vm that was bounced because nothing ever invoked the before() in the new instance of that vm.
> Presumably all of the DistributedTest Rules may fail in this way after using bounce:
> * DistributedDiskDirRule
> * DistributedRestoreSystemProperties
> * DistributedUseJacksonForJsonPathRule
> * SharedCountersRule
> * SharedErrorCollector
