Deploy model entrypoint

[hasan7n]

The aim is to have flexibility in creating model MLCubes from GaNDLF models. The user can now provide a custom entrypoint script for the MLCube which can act as a wrapper around calling gandlf_run. The goal is to NOT rely on having data input folder containing a csv file. Using a custom script, the model author can build a csv file before calling gandlf_run.

Proposed Changes

• Modify gandlf_deploy to allow custom entrypoint scripts for model deploy (like what we have for metrics deploy)
• add CI tests for deploy ( model + metrics deploy) and running the resulting MLCubes.
