[Task]: Create a script to train sklearn model for IT test.

What needs to happen?

Sklearn doesn't offer backward compatibility wrt models on newer versions. In the Sklearn IT tests, we use models trained manually and this can get outdated when there is an update to sklearn.

So to tackle this, we need to create a script which trains the sklearn models on the data and then publish this model to a GCS bucket, once this is done we can use this model to run Sklearn IT test.
