Most network-related metrics sent to MC by members are not used by MC. In a case of a large cluster, it can overload the MC.
To decrease the number of metrics sent to MC, their level has been changed to DEBUG.
In case those metrics are used by Prometheus Exporter via MC, the system property
hazelcast.metrics.debug.enabled
enables collecting debug metrics.Backport of: #21232
