[7.x][ML] Extend classification to support multiple classes (#53539) (#53597)
Prepares classification analysis to support more than just
two classes. It introduces a new parameter to the process config
which dictates the `num_classes` to the process. It also
changes the max classes limit to `30` provisionally.
