This doesn't seem like the right fix, this should be down in GaugeMetricFamily I think. Also a unittest would be good. |

@brian-brazil I've force-pushed away the original commit, and converted labelnames to a tuple in all MetricFamilies |

On Python 3 the labels of the
python_infometric is a reference to thedict_keysof the data object used to create it. This PR ensures all labelnames in MetricFamilies it are a static tuple instead.This PR is motivated by some broken tests in https://github.com/korfuri/django-prometheus with recent versions of prometheus-client: django-commons/django-prometheus#46 (comment)
Although the docs do not say Metrics should be serializable this change seems more in keeping with the intention that labels should be owned by the Metric and not a reference to an external object.
