AKKA_CLUSTER_BOOTSTRAP_SERVICE_NAME Value Should Default to `app` Label

[n3ziniuka5]

At the moment AKKA_CLUSTER_BOOTSTRAP_SERVICE_NAME is set as follows:

corev1.EnvVar{
  Name:  "AKKA_CLUSTER_BOOTSTRAP_SERVICE_NAME",
  Value: akkaCluster.Name,
},

The issue is that akka-discovery-kubernetes-api uses this value to query for pods that have the same value in app label. This label may not be the same as akkaCluster.Name
