Subject: [PATCH 1/3] feat: Support custom scopes and maxQueryResultRows

After this change the user can optionally control authorization scopes for BigQuery interaction and max rows for query results via environment variables, e.g.:

```shell
$ export BIGQUERY_SCOPES="https://www.googleapis.com/auth/bigquery,https://www.googleapis.com/auth/drive"

$ export BIGQUERY_MAX_QUERY_RESULT_ROWS=50
```
