feat: write a dedicated E2E test for the upgrade image

[mojtaba-esk]

There is no dedicated E2E test for the upgrade image that's why it does not brake any. There is one use case in the app e2e test which we have to update the sequence. i.e. Stop the instance first, upgrade the image, then Start the instance again.

This issue proposes to have a proper e2e test for upgrade image and possible changing some other params as well. like not only the image, but also for example update the start arguments.
