Status / Interfaces - Relinquish DHCP Lease

Send gratuitous DHCP release message to server.

Dependency:
To fully relinquish the DHCP lease, the "RELEASE" reason needs to be added to the /sbin/dhclient-script.
s/EXPIRE|FAIL)/EXPIRE|FAIL|RELEASE)/

Without the 'RELEASE' reason, the DHCP release message will still be sent to the server, however the local dhclient leases will not reflect the relinquishment. Therefore, DHCP renewal will do a DHCP request for the previous address rather than doing a DHCP discovery and being more likely to be assigned a different address.
