Support root-less execution

[thumannw]

Our Jenkins integration of Docker roughly looks as follows: Jenkins will create a container from the image and start it as a SSH server. Then it will connect to it via SSH as the user "jenkins". Hence, it has no root privileges inside the container. I think this approach is reasonable from a security perspective.

I tried this with an image derived from qodana-jvm-community:2022.3 but I got a permission denied error on /etc/passwd when executing /opt/idea/bin/qodana. Is Qodana trying to write to this file?

I have the feeling that the Qodana images would be more useful if they would support root-less execution. What do you think?
