SUMMARY

This error has happened a few times in the CI with 6.0...

ok: [testhost] => {
    "changed": false,
    "invocation": {
        "module_args": {
            "auth_mechanism": null,
            "connection_options": null,
            "force": false,

            "timeout": 10
        }
    },
    "msg": "An error occurred: While waiting for secondaries to catch up before stepping down, this node decided to step down for other reasons, full error: {'topologyVersion': {'processId': ObjectId('6341abdf1bdb4925796dc00f'), 'counter': 10}, 'ok': 0.0, 'errmsg': 'While waiting for secondaries to catch up before stepping down, this node decided to step down for other reasons', 'code': 189, 'codeName': 'PrimarySteppedDown'}"
}

As the intended event has happened anyway we should report this as a success, perhaps controlable via a parameter.
