Add bytes_billed to BigQueryAdapterResponse

[bruno-szdl]

resolves #560

Description

This PR adds the information of bytes_billed to the adapter response. This was made to have better monitoring of BQ's costs. (more detailed explanation of bytes_billed in #560).

Tests

I tested it in a local project. The bytes_billed can be seen in the response of the adapter, and they are different from bytes_processed in this case because the minimum bytes billed by BQ is 10MB. I just removed some information like model name and profiles directory.
