> Currently ContainersMonitor has only one default implementation ContainersMonitorImpl,
> After introducing Opportunistic Container, ContainersMonitor needs to monitor system
metrics and even dynamically adjust Opportunistic and Guaranteed resources in the cgroup,
so another ContainersMonitor may need to be implemented. 
> The current ContainerManagerImpl ContainersMonitorImpl direct new ContainerManagerImpl,
so ContainersMonitor need to be configurable.
