Description
Until v3 when we can finally standardize fitted model objects across algorithms (this has been a problem for years, see eg #41), I think we should provide a function in rstan to convert the list returned by optimizing() into a proper stanfit object consistent with vb() and sampling(). This would make a lot of people happy, or at least a bit less frustrated.

Research direction
Start by comparing the list returned by optimizing() with the stanfit objects produced by vb() and sampling(). Determine the conversion requirements needed for a consistent stanfit object, then verify that the proposed converter preserves the relevant fitted-model behavior.
