feat: run containerdebug in the background

[razvan]

Description

Part of stackabletech/issues#527

The containerdebug binary is executed in the Spark application pods by evaluating the _STACKABLE_PRE_HOOK in the run-spark.sh script. This script is the entrypoint of the Spark product image,

Had to reorganize the smoke test in order to fetch debug information while the Spark application is running. Fetching the containerdebug output after the job succeeds is not possible because the pods are terminated.

Also refactored the container's command and args properties to be more readable and more in line with other operators.
