Merge pull request juju#17125 from SimonRichardson/db-local-repl

juju#17125

When debugging or wanting to play with the db schema, it's handy to be able to apply the db to a given dqlite instance. The following does this for controllers and models.

For experimenting with the domain model this is really useful.

I've removed the infer schema, as I don't believe we need this anymore. It's not maintained and it served it purpose. If we do want it, we can use the older branches to get it.

<!-- Why this change is needed and what it does. -->
