[Predator] Add ``Project`` class and ``ClassifySuspect`` method to project classifier and component classifier.

Add ``Project`` class and ``ClassifySuspect`` method to project classifier and component classifier.

Also add validation for component classifier and project classifier.

N.B. Since I changed the config format of project classifier, so I included the validations in this cl.
