[ONOS-3662] Add CLI for control plane manager
- Implement CLI for enumerating control plane metrics stats
- Implement ControlResourceTypeCompleter
- Implement DiskResourceNameCompleter
- Implement NetworkResourceNameCompleter
- Implement ControlMessageDeviceIdCompleter
- Extract the control resource type and metrics in a separated
class for the sake of simplicity.
