Version outputs in target documents and rows

[blythed]

We should be doing this already, but Rome wasn't built in a day...

• In MongoDB, outputs are versioned in the documents, that means that we won't get inconsistencies, when a model is rolled back or updated
• In Ibis, there is one table per Model version.
