Model names with same prefix breaks API deployment

Description

When an API with a spec like in the following example gets deployed, the API breaks:

- name: multi-model-classifier
  kind: RealtimeAPI
  predictor:
    type: onnx
    path: predictor.py
    models:
      paths:
        - name: shufflenet
          model_path: ...
        - name: shufflenet-something
          model_path: ...

The reason is that in the cron.py script, we make extensive use of glob.glob(<model_directory> + "*/**", recursive=True), which will lead to inter-model path "bleeding".

Suggested solution

Replace all glob.glob(<model_directory> + "*/**", recursive=True) with glob.glob(os.path.join(<model_directory>, "**"), recursive=True) instead. There might be some gotchas here and there.
