In the multiversion passthroughs, this code will fail on an older version where featureFlagTimeseriesMetricIndexes does not exist.

        return assert
            .commandWorked(
                conn.adminCommand({getParameter: 1, featureFlagTimeseriesMetricIndexes: 1}))
            .featureFlagTimeseriesMetricIndexes.value;

We should either drop the assert and assume that this is not enabled if we can't get the parameter. Or we can simply blocklist all of these timeseries*.js tests on the various multiversion suites by requiring a particular FCV.
