### What changes were proposed in this pull request?
Fix the python streaming data source timeout issue for large trigger interval
For python streaming source, keep the long running worker archaetecture but
set the socket timeout to be infinity to avoid timeout error.
For python streaming sink, since StreamingWrite is also created per
microbatch in scala side, long running worker cannot be attached to s
StreamingWrite instance. Therefore we abandon the long running worker
architecture, simply call commit() or abort() and exit the worker and allow
spark to reuse worker for us.
### Why are the changes needed?
Currently we run long running python worker process for python streaming
source and sink to perform planning, commit and abort in driver side. Testing
indicate that current implementation cause connection timeout error when
streaming query has large trigger interval.
