Which problem is this feature request solving?

For local development, we use https://github.com/goccy/bigquery-emulator which emulates some functions of "full" BigQuery. To make it work with CloudQuery plugin, we would like to add an yaml option to point to non-default BigQuery API endpoint. It should be easily implemented.

Describe the solution you'd like

apiEndoint: localhost:9060

opts = append(opts, option.WithEndpoint(endpoint))
