There is at least one load balancer spec test that needs to be tested against a non-load balanced clusters: https://github.com/mongodb/specifications/blob/master/source/load-balancers/tests/non-lb-connection-establishment.yml#L8

Currently, this test is always skipped because we only run the test suite with a LB.

To fix this we can move test/load_balancer/test_load_balancer.py to test/test_load_balancer.py so that it runs with our standard test suite.
