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.
> DistributedTest rules should support bouncing and creating new VMs

> 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
