[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.
