Add BigQuery to Mongo operator at providers.mongo.transfers

[Wuerike]

Description

I've developed a BigQuery to MongoDB operator and I was thinking about contributing on adding it to the project.

I've basically merged BigQueryGetDataOperator (providers.google.cloud.operators) with MongoToS3Operator (providers.amazon.aws.transfers), following the same code style.

Has features like:

• Fetchs all fields on a line, or can receive witch fields should be fetch
• Stores the last fecthed line to read incrementaly between execution
• Supports this mongo methods: inserting, replacing and upserting

I'd like to know if its good enough, and if someone is available to help me during the process of contributing.

Use case/motivation

First of all, I'd like to make my first contribution on an open source project ever.

Talking about the application itself, it lacks of mongo operators, so I think it will be great to the community having one more example and application with it.

BigQuery already has a lot of operators this is why my idea was to add this on mongo folder.
