* kube: properly return the reason for connection disruption There are several cases where connection monitor can terminate an ongoing connection. Iddle timeout, certificate expiring among others are some reasons for the connection to be terminated. For Kubernetes access, the underlying error is never propagated back to the client so they don't receive the reason for the exec session being terminated. This PR fixes that by adding an hook to write the client error response into the connection error channel for clients to be aware. Part of #18496 * handle review comments * handle review comments
