Review Comment:
@ueshin @HyukjinKwon @gaogaotiantian
does it make sense to introduce such a env to identify where the current

available options might be:
- python worker spawned from executors
- python worker spawned from driver
- pyspark driver (in classic mode)
- pyspark client (in connect mode)
