and cleanup related code:
- Host.ipAddresses()
- DefaultHost.ipAddresses()
- HostDescription.ipAddress()
- DefaultHostDescription.ipAddress()
- HostService.getHostsByIp()
- HostManager.getHostsByIp()
- HostStore.getHosts()
- GossipHostStore.getHosts()
- SimpleHostStore.getHosts()
- ProxyArpService.known()
- ProxyArpManager.known()
As a result of the above cleanup, the "hosts" CLI command outputs
the IP addresses as "1.2.3.4" instead of "1.2.3.4/32".
Also, the following REST calls might be affected as well with
the above format replacement:
- REST POST: config/topology
- REST GET: topology/graph
