Plugin 0.13.0 API

All Implemented Interfaces:
```
public interface Server.Plugin

                    
```
Server.Plugin enables Server functionality to be augmented and/or observed.
Server.Plugin function execution is non-blocking, but occurs synchronously within Server proxy operations. Therefore, implement Server.Plugin functions judiciously, considering that long suspension time will impact Server throughput.
Server.Plugin function invocation is not thread-safe. Thus, perform any necessary synchronization in the Server.Plugin implementation.
