Add structured way to return rule evaluations

[jhrozek]

Currently the rule evaluations we returned are not really structured which is hard to consume from both scripts and clients like the minder UI.

We should come up with a way to return the results as structured parseable data.

@ethomson it sounds like we have epic to fix this quality issues.

@ethomson This seems like a duplicate of stacklok/minder-stories#3. I'm imagining the long detailed message would be a replacement for what is now in "issue reason".

After discussing with @rdimitrov @blkt @peppescg we determined that stacklok/minder-stories#3 is a better solution for the same problem.
