Allow for curbing logs while testing

[nikochiko]

Is your feature request related to a problem? Please describe.
Yes, I am writing tests for my graphene app. I need to test whether certain queries produce errors. When client.execute(...)is run, this logs an annoying graphql.error.located_error.GraphQLLocatedError. I cannot even use pytest.raises or self.assertRaises in unittest because it only logs without actually raising an error. It even logs the entire traceback which is even more annoying.

Describe the solution you'd like
It'd be much better if we had a solution to have a loglevel flag in client.execute(...) or some other way to disable logging of those specific errors.

Describe alternatives you've considered
I have considered disabling all error logs from the test runner (with logging.disable(logging.ERROR)). I am going with this for now but I don't want to miss out on other important logs which may help in surfacing faulty tests.
