VHID changes do not apply immediately on secondary

Virtual IP Addresses
Description
When changing the VHID on the primary, it's applied immediately on the primary and synced to the secondary so its config.xml is correct, but the secondary does not update its configured CARP IPs with the correct VHID. So you end up with dual master status, with each on a different VHID.
This does not happen as expected. The VHID does sync in the config, but that change does not propagate to the actual CARP interface. I suspect this is due to the issue I found in ticket #643
It won't update a CARP interface on sync, only at boot or when you edit/save the VIP.

Just tested this again, and it is still a problem. On the secondary box, the VHID changes under the CARP settings screen, but on Status > CARP, the interface name is still the old VHID, and even though it shows "backup" in the GUI, the output of ifconfig -a shows it as master.
So the logic for renaming the CARP VIP interface (e.g. vip55 -> vip41) as well as changing the VHID on the interface isn't happening after the xmlrpc sync.

I implemented the fix for this.
Though i think it is better to put even the reloading of carps through rpcxml in the same way i did for destroying the old ones, instead of relying on a xmlrpc call to bring them up again!
