Hide sensitive information from container build logs and minimize logs by default

[leochr]

Evaluate and hide passwords and sensitive information from the container image build logs. Even when verbose is enabled, these should be hidden.

We should also minimize the build logs by default and show additional information only when verbose is enabled.

Any errors during the build process should always appear in build logs (whether verbose is enabled).
