Instance-Level Self-Hosted Model serving configuration

When a customer self-hosts a model, the existence of this model along with it's connectivity information needs to be declared to GitLab Rails. GitLab Rails is responsible for exposing this information to the AI Gateway.

Once a model has been declared, it can be assigned to specific GitLab Duo functions as described in Configuration option to select model (#454323 - closed)

This configuration is added in the instance-level configuration settings.
