    [FLINK-8122] [table] Name all built-in table sinks and sources

    ## What is the purpose of the change
    
    This PR adds names for all built-in table sources and sinks.
    
    ## Brief change log
    
      - Adds a `getRuntimeName()` method which returns a string consisting of the class name
and the field names to the `TableSource` and `TableSink` traits.
      - Implements `getRuntimeName()` in all sub-sources and sub-sinks written in **Java**
(since it seems they cannot extend the implementations in scala traits).
      - Names the `DataSources` and `DataSinks` with the `getRuntimeName()` after creating
the stream operators in all built-in table sinks and sources.
      - To avoid NPE, adds a mock `DataStreamSink`(`DataStreamSource`) when invoking `Environment.addSource()`
(`DataStream.addSink()`) in some existing tests.
