[SPARK-22554][PYTHON] Add a config to control if PySpark should use daemon
or not
## What changes were proposed in this pull request?
This PR proposes to add a flag to control if PySpark should use daemon or
not.
Actually, SparkR already has a flag for useDaemon:

It'd be great if we have this flag too. It makes easier to test Windows
specific issue.
## How was this patch tested?
Manually tested.
