[SPARK-16031] Add debug-only socket source in Structured Streaming
## What changes were proposed in this pull request?
This patch adds a text-based socket source similar to the one in Spark
Streaming for debugging and tutorials. The source is clearly marked as
debug-only so that users don't try to run it in production applications,
because this type of source cannot provide HA without storing a lot of state in
Spark.
## How was this patch tested?
Manual tests in sparkShell for now. The other Spark Streaming socket source
doesn't seem to have a unit test, but we can add one.
