What this PR does
Modify the utilization based ingester read path limiter to base memory utilization on Go heap size instead of RSS from /proc/self/ (Linux procfs). The motivation is that we have experienced significant practical divergence between procfs and cAdvisor (container) memory measurements, and after a design discussion we've arrived at trying to track the Go heap size instead for simplicity.
