cubicweb #17289677 data validation from the yams schema [open]

It would be useful to have functions that could take data (instances of the entity classes, maybe) and return a list of schema violations (or an empty list if everything is ok).

We probably have a part of that already, but I do not think it can be called without inserting data.
