bigquery: Add ability to manage credentials to `google_bigquery_connection`.  This field is required as the resource is not useful without them.

Is this connected to any issues?

Could the cloud_sql part of the resource ever worked without credentials? It's a little spooky to add a required field to an existing resource.

@ndmckinley thanks for this!

@rileykarson credential was only added when bigquery connection moved into GA, prior to that the property simply wasn't settable via the api
