Add loadBalancer.labels support (#276)

* Add loadBalancer.labels support

For example, cilium LB IPAM uses labels to match pool with a service (https://docs.cilium.io/en/latest/network/lb-ipam/)

* bump version of the chart

* make it minor release

* fix trailing slash that break validation

* fix empty annotation object
