Auditing on overriden keys in contexts

[AvivRubys]

Given context overriden keys can be edited using APIs, it could be helpful to have auditing on them. I think that at the very least some sort of "last edited at/by" field could be useful. What do you think?

It might be interesting, but less trivial to implement full editing as override keys are saved on context which is currently mutable in terms of API design for context driver.

Adding mutable fields of "@LastUpdated" and "@LastUpdatedBy" should be possible.

We can do it in the editor by adding these fields on every PATCH operation
