Generic agent-side API for VM start/stop
Introduce an API that all backends can use to find out when a VM starts
up or shuts down. Currently, all backends re-implement this
functionality using jvmstat explicitly. With an explicit API for this,
we will have less duplicated code for each plugin and we can
change/improve the implementation that detects when VMs start or stop
without having to change each plugin.
All classes implementing VmStatusChangeListener registered as OSGi
services now get notified about the VM's pid when a vm starts or stops.
The GC backend now obtains the pid from this new API but still uses the
MonitoredVm class form jvmstat connect to the VM and gather data.
