Hardcoded service selector

[kop]

Hi,

I was a bit confused recently why kube-lego is not working on my setup. After some debugging, I've noticed that it replaced all selectors I've defined in service.yml with just app=kube-lego.

Is it really needed? For example, I'm using a bit different naming and had to add extra label just to let it work. If not, at least it would be great to document this somewhere.

Will include this into the docs of the next release

Any update here? This is a major problem which makes kube-lego basically unusable on 1.6 w/ RBAC enabled.
