CLOUDSTACK-6434: Make RvR advert_int configurable
In some network environment, 1*3 seconds by default make RvR setup too
sensitive. A configurable parameter would be better for fitting different
network environments.
> Enable redundant virtual router to configure interval for VRRP broadcast

> Originally RvR are set VRRP broadcast interval to 1s, which means if BACKUP
> didn't get message in 3 x 1s(miss 3 times), then it would kick in.
> In some heavy network environment, 3s may be too sensitive and cause
> BACKUP/MASTER router switch back and forth. In this kind of environment, we
> need a way to specify interval for VRRP broadcast, to prevent unnecessary and
> mostly troubled switch back and forth for RvR.
