s3: Add "smbcontrol winbindd ip-dropped <local-ip>"
This is supposed to improve the winbind reconnect time after an ip address has been moved away from a box. Any kind of HA scenario will benefit from this, because winbindd does not have to wait for the TCP timeout to kick in when a local IP address has been dropped and DC replies are not received anymore.
