It would cover the configuration of DHCPElement, VirtualRouterElement and
RedundantVirtualRouterElement.
Also add foreign key in domain_router table to reflect the domain_router is
created from which element and use what configuration.
Force stop the router would release all the resources it used, but router may
still running. Add a column "stop_pending" in the database, and stop it when the
router come back.
Admin would able to choose to force destroy such router, then recover the
network using restartNetwork command with cleanup=false.

And all modification to the scripts till
commit 4e3942462ed3fde3a3d7011e95839e2128fba514
logging changes
in the master branch.
This patch enable redundant virtual routers.
1. To enable this feature, db need to be updated using follow SQL by now(we
would get a UI way later):
UPDATE network_offerings SET redundant_router=1 WHERE guest_type="Virtual" AND
system_only=0;
2. System would try to start up two routers at different hosts. But if there is
only one host in the zone, system would start up two routers on it.
3. The failover part is using keepalived, and connection tracking part is using
conntrackd. There would be one master router and one backup router. The status
of router(master or backup) can be query from the database table domain_router
now. Management server would update the status every 30s by default.
4. The routers for the same zone would use same external NIC(same ip and mac).
The script used for fail-over would ensure only one external NIC present in the
network at any time.
5. Currently management server don't got the ability to stop one of router is
both of them reported as master. The feature is in the todo list.
After two routers start up, disconnect anyone of them, the guest network
shouldn't be affected, and established connection(http, ssh, etc.) should still
works. The fail-over on gateway part should be 3~4 seconds.
Currently the patch works with KVM. Would deal with vmware and XenServer soon.
status 7348: resolved fixed
More fixes:
* Update user_statistics on each domR stop/reboot
* Reset dhcpData/userData as a part of domR stop/reboot
* More logging for domR commands
status 1974: resolved fixed
It's a synced API, which just update router vm's service offering,
parameter: router id, service offering id,
return: ture on successfull, otherwise false
