defined by the Kubernetes documentation, now that
failure-domain.beta.kubernetes.io/region has been deprecated.

### location
Kilo allows nodes in different logical or physical locations to route packets to one-another.
In order to know what connections to create, Kilo needs to know which nodes are in each location.
Kilo will try to infer each node's location from the [failure-domain.beta.kubernetes.io/region](https://kubernetes.io/docs/reference/kubernetes-api/labels-annotations-taints/#failure-domain-beta-kubernetes-io-region) node label.
Kilo will try to infer each node's location from the [topology.kubernetes.io/region](https://kubernetes.io/docs/reference/kubernetes-api/labels-annotations-taints/#topologykubernetesioregion) node label.
If the label is not present for a node, for example if running a bare-metal cluster or on an unsupported cloud provider, then the location annotation should be specified.
_Note_: all nodes without a defined location will be considered to be in the default location `""`.
