Display access permissions for models on model detailed view

[appukuttan-shailesh]

Partly related to #191

As a user cannot edit/update all the models that they see in the model catalog, it would be useful to have icons (maybe inside a "Permissions" box?) that indicate whether a user has only READ permissions for that specific model, or both READ and WRITE.

Often it is not easy to identify why you don't see the "EDIT" options for some of the models. Also, you cannot run a test on any model that you see in the model catalog. You need to have WRITE permissions for these models.

For APIs,
READ = GET
WRITE = PUT/POST

@apdavison : Go ahead with this?

Why do you need write permission to run a test on a model?

[appukuttan-shailesh]

To be more accurate... running the test does not require write, but to register the new results (POST) we require write permission.

[apdavison]

Why?

[appukuttan-shailesh]

If the model is public but the user is not a member of the model's host Collab. The user can see the model in the model catalog, but cannot PUT/POST.

This is as per the current implementation. Found an example of this last week.

[apdavison]

No permissions should be required to post test results (the user just needs an HBP account).

If there are related data, then the user should specify a collab for which he/she has permission to write to the storage.

Even if writing to storage fails, however, the result should still be registered.

[apdavison]

On the topic of the issue, I agree it would be useful to display a small box that explains the permissions.

This continues to be a problem... should we take this up on priority?
