dhcp-manager: don't remove leases: they can actually be useful...

[Thomas NOEL]

Binary package hint: network-manager

Ubuntu release: Jaunty
NetworkManager : 0.7.1~rc4.1.cf199a964-0ubuntu2

When I unplug/plug my PC on my DHCP network, sometimes I don't get the same IP, even if the IP is free.

The problem is that when deactive an interface, NM delete the /var/lib/dhcp3/dhclient-<interface>.leases file ! Doing this, it's impossible for dhclient to ask for the _same_ IP address when the interface is re-activated.

It's a really annoying bug when you have to manage a network of Jaunty machines : all IP addresses can change if you just reboot a switch (deactive/reactive signal on all interfaces)... If /home is NFS-mounted, all PC just stop to work.

The patch included fix this issue. It's from the NM git, see the commit here :
