[UI] Create a model

Context

In #384718 (closed) a model registry was suggested derived from the Package Registry. The model registry is a version control system for models that provides APIs to store and retrieve models and model-related artifacts

Assumed problem

Data scientists are not used to use CLI or CI/CD to populate a model registry. They are more used to using a UI to accomplish this. Currently, it's only possible to add a model to the model registry via ML Flow Client

How might we make the handoff between ML and Ops easier?

Proposal

• Add a UI to add/import/register a model with the model registry.
• Add a UI to add/import/registry a version of an existing model in the model registry.

States:

• Button to add model to model list page, model detail page
• User inputs model name, model version, other things? Description?
• Upload dialog and/or drag and drop
• Uploading progress state
• Error uploading (model already exists, file too large, invalid file type, other errors?...)
• Uploading success state

Considerations

A UI to upload models could be reused as a way to upload packages to the Package Registry
