[BP MB-33872] - Set ReadTimeout and WriteTimeout explicitly in eventing http server

The http server in eventing uses http.ListenAndServe to setup the server. It would be good to explicitly set ReadTimeout and WriteTimeout on the Server object to ensure very slow clients don't hold up connections. If the timeouts are not set, they default to off (no timeout) causing clients to hold up connections by reading slowly. This may lead to too many files open errors as seen in some customer deployments.
