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.

- Update system vm_instance's template_id if it does not match the system vm template.
- Use _templateDao.findSystemVMTemplate to find the latest system vm template.
These include five new API cmds as well as changes to deployVirtualMachine to
specify an optional name of an SSH key to pass to the VM when starting. When
an SSH key is specified with a password-enabled template the newly created
password is encrypted with the SSH public key and can be retrieved via the
getVMPassword cmd. It is then the user's responsibility to decrypt retrieved
passwords with the correct SSH private key.

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 7517: resolved fixed
Name should follow these rules:
* must be between 1 and 63 characters long and may contain only the ASCII letters 'a' through 'z', the digits '0' through '9', and the hyphen ('-').
* can not start with a hyphen, and must not end with a hyphen
Once name is set (during vm deploy), it can't be modified.
