Add toggle to enable/disable models from being able to load.

Is your feature request related to a problem? Please describe.
No - Feature request.

Describe the solution you'd like
Toggle on the loaded models so one can disable them being loaded.

Describe alternatives you've considered
Deleting model, but would like them to remain in my collection.

Additional context
I now have a large collection of models but do not want some of them loaded on demand esp. given memory contraints.

I may get time to do this myself and submit a PR.

Yes, I'd very much like this as well!
The workaround I've done currently is to move the files into another folder so they're not seen by LocalAI.
Not ideal, so I'd love a toggle instead!
