### Summary
Explicitly replaces all old docs pages with a link to the new docs. This
was required because 404 redirects didn't work for pages that previously
existed, though they worked non-existing paths that never existed.
### Description
This adds the basic implementation of pushing the generated json output
of partition to mongodb. None of this code provisions the mondo db
instance so things like adding a search index around the embedding
content must be done by the user. Any sort of schema validation would
also have to take place via user-specific configuration on the database.
This update makes no assumptions about the configuration of the database
itself.
