Support more credential type for BigQuery

[goldmedal]

Description

Currenlty, we only supports to connect BigQuery using the service account.

wren-engine/ibis-server/app/model/data_source.py

Line 101 in 8c16406

credentials = service_account.Credentials.from_service_account_info(

It's better to support more way to connect BigQuery. (e.g user account credentials)
I saw ibis-project use pydata-google-auth to make the credentials. It seems a good way to support other auth way.
