Only run exhaust ismaster metrics tests in the integration_tests_standalone and integration_tests_sharded suites

It looks like the ReplicaSetMonitor now uses exhaust streamable isMaster by default. This is problematic for our exhaust isMaster metrics integration tests as these tests assume no other clients will initiate exhaust streams with the server. Naturally, the metrics received can end up being incorrect. We should exclude our tests from being run in the integration_tests_replset suite.
