Migrate the existing checker / suggester code to instead use the new validator framework. We need to add,
- A printfCheck validator that is insertable but not enforced.
- A validator for variable - {link_end} that is insertable and not enforced.
- A validator for HTML entities …, that is insertable but not enforced..
We'll need to update the YAML configuration file located here - https://phabricator.wikimedia.org/diffusion/GTWN/browse/master/groups/
