Is your feature request related to a problem? Please describe.
As a user I use Job interfaces like Databricks workflows. I want to be able to set job parameters in a simple way without changing the config files.
So far I only can set the environment variables, which is not really user-friendly (or Java properties, which are even more complicated in the current environment).

Describe the solution you'd like
I would like to be able to overwrite a Hocon variable using a command line argument (SDLB argument), like

... sdl-spark --config [config-file] --feed-sel [feed] --config-value-overwrite env.case.variable=value1

Here the mentioned parameter "config-value-overwrite" should overwrite the setting of the env.case.variable variable with the new value value1
