google provider - add project_id to GoogleBaseHook

[raphaelauv]

the BigQueryHook based on GoogleBaseHook do not accept an explicit project_id

this PR add this feature

[mik-laj]

Any method that needs project ID uses the fallback_to_default_project_id decorator, so I'm not sure if we need another way to configure the project ID.

yes but I'm thinking about the hook itself , currently if I call get_client

I have to give the project_id myself, example :

    def execute(self, context):
        bq_hook = BigQueryHook(
            bigquery_conn_id=self.bigquery_conn_id,
            use_legacy_sql=self.use_legacy_sql,
            delegate_to=self.delegate_to,
            location=self.location,
            impersonation_chain=self.impersonation_chain,
        )

        conn = bq_hook.get_client(project_id=self.project_id, location=self.location)

        ...
