Fix nginx config error parsing configmap (aenix-io#200)

The error manifests as:

W0705 16:07:35.694677 7 configmap.go:431] unexpected error merging
defaults: 2 error(s) decoding:

* cannot parse 'proxy-connect-timeout' as int: strconv.ParseInt: parsing
"10s": invalid syntax
* cannot parse 'proxy-read-timeout' as int: strconv.ParseInt: parsing
"10s": invalid syntax

I came across this trying to understand why my nginx ingress addon
config isn't working, (this didn't help, but at least the warning is
gone now.)

I'll continue to try to debug, but I think this can merge any time
