project_id(String) — Identifier for a BigQuery project. If not
present, the default project for the credentials is used.
credentials(String, Hash, Google::Auth::Credentials) — The path to
the keyfile as a String, the contents of the keyfile as a Hash, or a
Google::Auth::Credentials object. (SeeBigquery::Credentials)
