   * A simple endpoint snitch implementation that assumes datacenter and rack information is encoded
   * in the 2nd and 3rd octets of the ip address, respectively.
   * As with all snitches post CEP-21, this retrieves Location for remote peers from ClusterMetadata.
   * Local location is derived from (broadcast) ip address and added to ClusterMetadata during node
   * registration. Every member of the cluster is required to do this, hence remote peers' Location
   * can always be retrieved, consistently.
