      Original Downstream Change Summary

      ObservableMutex tags and ergo lock contention metrics names in serverStatus have been changed to follow lowerCamelCase, e.g., `serverStatus.lockContentionMetrics.ConnectionPool::_mutex.exclusive.waitCycles` is outdated; `serverStatus.lockContentionMetrics.connectionPoolMutex.exclusive.waitCycles` is the new name. Consumers will have to update these metric names to continue receiving lock contention stats.

      Description of Linked Ticket

      SPM-3828 introduced the ObservableMutex API, but these metrics are only exported to FTDC right now. Add native support for OpenTelemetry with the option to additionally export to FTDC. The serverStatus naming convention should be followed.
