Remove confusing error message due to timeout/watch

[szuecs]

These error messages coming from glog, but we should delete these log entries, because the behaviour is intended and the client-go timeout works for WATCH, but not for all other API calls.

...

Maybe we just drop the timeout on the client-go configuration since it doesn't seem to work anyway :unamused:

We have to investigate what happens if we use no Timeout, but the custom Transport introduced in https://github.com/zalando-incubator/stackset-controller/pull/24
