init command to generate a kitfile

[bmicklea]

Implement an init command to initialize a kitfile on a given repository. The command should be able to introspect the folder and suggests a kitfile. It should also be able to use artifacts from different frameworks like MLFlow to initialize the information

The init command is an interactive command. It should be able to discover artifacts on a folder like jupyter notebooks, csv. json, well known serialized models and interactively complete the generation of the kitfile.

Also init should recognize and generate kitfile from the info generated by MLFlow's save_model
