Just curious - why do we need to call int() here? I'm not opposed just for safety reasons, but x.version is already a number right?

Actually model version is str: link. So it's safer to convert it into int here.

Given the added complexity, it may be good to have an example of each URI type in the branch so that it's clear exactly which case maps to which tuple

What changes are proposed in this pull request?
Support specifying 'latest' in model URI like
models:/<model_name>/latestto get the latest version of a model regardless of the stage.Also fix a bug in
sqlalchemy_store.get_latest_versions(): when nostageargument is specified, it should return the latest versions of all stages. Now it's only returning latest versions for active stages.stageargument is specifiedIn #4250, Anil also suggested supporting model URI formats like
models:/<model_name>/latest-nto get the nth to last model version. But it requires too big of a change (e.g. extending theRegisteredModelclass and the corresponding proto message to store not only the latest versions of a model, but also all versions). It may not be worth it to make such a big change for this small "latest-n" feature. So I'm not doing this in this PR.How is this patch tested?
