Oliver Gould 54d2bcb0ec controller: Increase HTTP ReadHeaderTimeout to 15s (#9272) ... 04a66ba added a `ReadHeaderTimeout` to our HTTP servers (at gosec's insistence). We chose a fairly arbitrary timeout of 10s. This configuration causes any connection that has been idle for 10s to be torn down by the server. Unfortunately, this timeout value matches the default Kubernetes probe interval and the default linkerd-viz scrape interval. This can cause probes to race the timeout so that the connection is healthy from the proxy's point of view and a request is sent on the connection exactly as the server drops the connection. These request failures cause controller success rate to appear degraded. To correct this, this change raises the timeout to 15s so that the timeout no longer matches the default probe interval. The proxy's HTTP client is supposed to [retry] requests that encounter this type of error. We should follow up by doing more research into why that is not occurring in this situation.
