Alex Ellis (VMware) 52c27e227a Tune HTTP client for concurrency ...

- due to what appears to be a frequent issue with the Go HTTP
client some tweaks were needed to the HTTP client used for
reverse proxying to prevent CoreDNS from rejecting connections.

The following PRs / commits implement similar changes in
Prometheus and Minio.

https://github.com/prometheus/prometheus/pull/3592
https://github.com/minio/minio/pull/5860

Under a 3-node (1-master) kubeadm cluster running on bare
metal with Ubuntu 18.04 I was able to send 100k requests
with 1000 being concurrent with no errors being returned
by hey.

```
hey -n 100000 -c 1000 -m=POST -d="hi" \
  http://192.168.0.26:31112/function/go-echo
```

The go-echo function is based upon the golang-http
template in the function store using the of-watchdog.
