Report warnings as errors + How to update configuration YAML for newer versions

[obruendl]

Hi Jeremiah,

I am using VSG to lint my open-source FPGA standard library Open Logic.

I have two questions:

1. Is there a way to report warnings as errors? For development I tend to accept some warnings until my code works but in CI I would like the pipeline to fail if there are any warnings left.
2. I have a YAML configuration file that works for vsg 3.27. However, if I upgrade to a newer version (3.3.0 or higher) it fails with various errors for the indentation configuration. Can you provide some guidance how I can update the YAML to work with newer configurations? I couldn't find an exact documentation what changed in the configuration files - and for maintenance reasons of course it is difficult to always sort out and apply many manual changes if vsg is upgraded to a newer version (in this case even a minor version increment).
