Customer Personality Analysis training + flask app

[vaasu2002]

Made a machine learning training pipeline for Customer Personality Analysis. The training pipeline contains 4 components- Data Ingestion, Data Validation, Data Transformation, and Model Trainer. The data is downloaded from the S3 bucket in the data ingestion component. The trained model is deployed in the Flask app, where we can perform single prediction as well as re-training using /train API. The problem is actually a clustering problem. I did modular coding and made a small package of customer_personality.
