Add a debug mode for file processing output

[diwu001]

When we debug some transactions in data-deal, we want to know where each field is generated from. So it would be great to have a debug mode for file_processing to help us analyze the output fields.

Currently we already have a debug mode in web service, and we can add the following fields to the output of file processing as debug mode:

• Agg_Name,
• CNN: {label, merchant_score},
• RNN_merchant_name,
• input: {city, state, postal_code, country, store_number, phone_number, website_url},
• agg_search: {address, city, latitude, longitude, list_name, phone_number, source_url, state, store_number, zip_code},
• factual_search: {street, city, latitude, longitude, merchant_name, phone_number, website, state, store_id, postal_code, confidence_score, country, source_merchant_id}
