[Feature implementation] Enterprise RAG application upgrade functionality

[jpiaseck]

Currently we are not able to upgrade Enterprise RAG from older version to never version.

There is possibility to run:

 ./install_chatqna.sh --auth --telemetry --deploy xeon_torch_llm_guard --ui --upgrade

but it would not work as:
would fail during updating deployment as istio is blocking update

similar issue would be faced when trying to update telemetry.

Goal is to have ability to update configurations/erag version without crash
