Freeze models for healing migration

Take a snapshot of all models from the code base at the time when the
healing migration merges. The healing migration needs this frozen view
of the models to be available (even as the models change in the future)
to compare with the current DB schema. The healing migration will use
this comparison to heal the schema.

The module provides all database models at current HEAD.
Its purpose is to create comparable metadata with current database schema.
Based on this comparison database can be healed with healing migration.
