Support custom reset_timedout_connection

[dovics]

What do you want to happen?

In our environment, we cannot control the connection timeout set in the client. After the connection times out, users are confused when they receive the reset message directly due to the following configuration. We hope that the connection will be closed normally.

ingress-nginx/rootfs/etc/nginx/template/nginx.tmpl

Line 259 in 79c684f

reset_timedout_connection on;

We want it to be configurable in the ConfigMap
