Is there a way not to expose process_* metrics?

As the title says, is there a way not to expose process_* metrics?

I've given a quick look at the code and prom_collector_registry_t->disable_process_metrics seems the knob I'm looking for, but it seems it's never used. Besides, it seems that collecting and exposing process metrics is enabled by default:

prometheus-client-c/prom/src/prom_collector_registry.c

Lines 91 to 99 in c57034d

	int prom_collector_registry_default_init(void) {
	if (PROM_COLLECTOR_REGISTRY_DEFAULT != NULL) return 0;
	PROM_COLLECTOR_REGISTRY_DEFAULT = prom_collector_registry_new("default");
	if (PROM_COLLECTOR_REGISTRY_DEFAULT) {
	return prom_collector_registry_enable_process_metrics(PROM_COLLECTOR_REGISTRY_DEFAULT);
	}
	return 1;
	}

I guess that one could always edit and recompile the library but I was looking for something out of the box.

If its been enabled by default for some time, it seems best to add a new cli option to turn them off via that disable_process_metrics setting you found.

@nicolacdnll are you going to put a PR for this?

I might, but definitely not in the upcoming 2-3 weeks.
