Investigate options to reduce labels per series

[davidusken]

Thank you very much for providing a great SimpleMDM Prometheus Exporter! I was just doing some testing and realized that one of the series, simplemdm_device_info has a total of 79 labels. The default limit of Mimir is 30, however this can be increased. Regardless, it would probably make sense to look into reducing the amount of labels per series and instead increase the amount of series (at least that seems to be the way that many other exporters do it)

Like I said, the limit can just be increased so feel free to close if not interested, just some general feedback :)
