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.
Also fixed a couple of other problems:
* verify security group ids before vm creation
* don't create "default" security group (if missing) as a part of deployVm process when vm is deployed from vmWare template
status 9873: resolved fixed
Following fixes were made as a part of the checkin:
* When deploy user vm and SG doesn't exist in the DB, create it automatically.
* SecurityGroup enabled use vm start: if map to default group is not present in security_group_vm_map table, create one.
* Added "name" (securityGroupName) parameter back to deleteSecurityGroup/authorizeSecurityGroupIngress/deployVm. Mutually exclusive with security group id parameter.

The type cast should be done after making sure that the command was successful. Otherwise you may have the base Answer returned.
Changes:
- Throw an exception if the deployment plan passed into start() cannot be satisfied by the current constraints (such as root volume is already created in a pool in a different
cluster).
