Allow to configure superuser account from environment variables

• [X] I've searched through the current issues to make sure this feature hasn't been requested already.

Motivation

For automatic deployment on kubernetes cluster, I need to be able to inject in the solution a custom superuser account and a custom default password which can be store either as Secrets in K8s or as GitLab secrets for example.

Suggested solution

A solution could be to amend the setup_suite.sh file to use environment variables instead of the hard coded values.

Alternatives considered

@AlexGacon thanks for the suggestion, I'm curios do you have some G3W-SUITE instance on kubernetes to look at?

[AlexGacon]

I am working on it but it won't be publicly available.

@wlorenzetti I will be at FOSS4G EU next week if you want to discuss this.
