Too many haproxy processes running in default-router pod on RHOCP node

Issue

• High number of haproxy processes in default-router pod causing high load average on RHOCP node.
• Ingress node memory consumption is growing until all memory is consumed, causing OOM (out-of-memory) killing of random processes and overall ingress node outage.
• Router pods are intermittently restarting without explanation a few times every day/hours.
