ISSUE-690: Create AI model whitelist configuration

[Naragod]

Description:

We wish to dynamically whitelist AI models available for use. To prevent the potential exposure of sensitive data when autograding/autotesting assignments, we wish to restrict usage to remote models.

Implementation

Allow users when creating an assignment the ability to submit a whitelist of available models. When the autotest is ran, any models used missing from this list will fail to execute.

Hi @Naragod , I think you misunderstood the requirements for this Issue. We specifically would like to whitelist what is allowed to put in the remote_url argument for the RemoteModel class.

Will document here what we spoke about: We will not use a whitelist file but instead put the list of allowed endpoint urls in the settings.yml file.

I'm getting an import error from here when running the AI test. Did you encounter this?
