Since we've upgraded the software, we now need to upgrade our codebase accordingly.

I will list here things that need to be done and then spawn out tickets/tasks accordingly:

• Convert all validate_* calls to the legacy-compat versions, or (better) use typed variables in classes and modules
• Convert all hiera() calls to calls of the lookup function
• Convert the hiera backends to the new API
• Convert the custom parser functions to the new API
• Disable automatic hiera autolookups
