GAUGE multiprocess_mode use 'livemostrecent'，the metrics will not be removed

[ELvisZxc]

I define a Gauge with "livemostrecent" mode, I can find the metrics in prometheus even the exporter no longer provides this metric (gauge.clear()). I expect it will auto-removed after call gauge.clear().

Version:

python : 3.10
prometheus-client==0.19.0

any suggestions?

Hello, this is a subset of #916, so I am going to close it as a duplicate. I would love a contribution to fix this, or else will try to get to it when I have time.
