[DOP-18743] Set default jobDescription

[dolfinus]

Change Summary

Set jobDescription in any method which interact with Spark in some way. Examples:

This does not work if Spark action was triggered outside of onETL methods, e.g. user called df.count() or df.toPandas():

It's hard to write tests on this because jobDescription is reset just before method returned some result.
