release-note/small
On machines with high core count, not setting the `--concurrency` flag of Envoy results in Envoy defaulting to having as many worker threads as HW threads. In low-load scenarios, this creates very high CPU and memory usage unnecessarily. This fixes the issue by adding a concurrency flag and plumbing it through the `ContourDeployment` CRD.
