Log values.yaml in case of errors and filtering sensitive values

[meyskens]

in #153 the debug log for values was removed.
This adds it back in a form where it replaces sensitive values.

@meyskens #150 also includes the introduction of new attribute - overrides, which will be saved in state. Maybe that could be used for the debugging purposes too ?

LGTM

@legal90 Your comment is more related to #150 than about the code in this very PR, isn't it?

[legal90]

@meyskens Ah, you're right. Sorry, I didn't notice that this is a PR, no an issue (feature proposal).
I actually like the implementation of sensitive data suppression here 👍

And we might need to rework #150 a little bit, after this one is merged.
