AutoML backend accepts 'ignored_columns' containing one of response, fold, weights column

[exalate-issue-sync]

Discovered this when using Flow.
Python+R clients are doing the filtering on their side, but it should also be done on backend.

when setting up AutoML, we should ensure that ignored_columns get automatically those columns removed if present, also alerting the user with an eventLog message:

• response_column
• fold_column
• weights_column
