UI Changes for Model Serving

There are a number of small UX issues around model serving that need to be addressed:

Models section of a project

• Once a model server is configured, hide the Configure server button (this is a temporary change until we support multiple servers per project)
• Once a model server is configured, open the Deployed models row expansion by default
• include an empty state if there are no deployed models
• auto scroll the page so that all deployed models or the empty state text are visible when the row is expanded

• Move deploy model button to an inline action in the model server row

Configure server modal

• Allow model server replicas to scale to 0
• For Custom model server size, (1) show units dropdowns per the mockups, and (2) allow Request and Limit to be the same value

Deploy model modal

• Model framework field should be required
• Model location field should be required when Existing model location is selected

Model serving page

• Change page title to "Model serving"
• Change the "Serve model" button label to "Deploy model"
• Add filtering by Project to the deployed models table
• This is a nit... it looks like there's extra whitespace between the page description (text under the title) and the table
