[kubernetes] K8s 1.8 changed ReplicaSet naming

See original GitHub issue

K8s 1.8 changed the naming scheme for some objects, including ReplicaSets, in this commit, notably the pod template hash is now encoded as a hexadecimal, rather than decimal. This breaks the assumption in kubeutil about the name being all (base 10) digits. This is called for example by get_pod_creator_tags, which in turn is used by the docker integration. Due to this, docker metrics can’t resolve ReplicaSets to their creating Deployment.

@ChipmunkV we infer the deployment name from the replicaset name, not the pod name, see https://github.com/DataDog/dd-agent/blob/80ceba8a0789e20d0b5b1bc740bd26e34ebda019/utils/kubernetes/kubeutil.py#L374
