[stable/traefik] Add loadBalancerIP to the Traefik service template (#1607)

* Added loadBalancerIP too the traefik service template. This can be set through a value called googleStaticIP, which is None by default. This was needed to make it possible to set up your loadbalancer with helm and assigning an already reserverd static ip in GCP. Im not sure if this works on other clouds, therefor have I called it googleStaticIP. Updated README with proper values

* Made value and template cloud specific

* changed it to loadbalancerIP

* Bump version for feature

* another version bump
