Deleted DHCP Host Still Resolves in DNS

When deleting a DHCP host, the DNS reservation should be removed as well. However there is a bug in which these hosts are never deleted.

Delete hosts in /etc/hosts which are no longer used and reboot the router.

DHCP server on the edgerouter needs to update the hosts file when new IP's are issued.
