BigQuery emultator source proposal

[vladDotH]

Sometimes I work with this bigquery emulator: https://github.com/goccy/bigquery-emulator.
BQ API and its client libraries allow you to specify API endpoint (or grpc client) to BigQuery that makes it possible to use emulator in my programs (e.g. tests and CI).

So is there a way to do it in Trino? I tried to use proxy settings but it doesn`t work, and I suppose it will not. It would be awesome if we could specify API and GRPC urls in catalog properties.
