The current deployment workflow relies on the network allowing multicast traffic for VRRP management of the VIP addresses, this PR updates keepalived to support also unicast mode. To enable unicast keepalived, keepalived.conf in each node should include all the relevant nodes (including the bootstrap node ) IP addresses, to support this requirement the bootstrap node will run a simple server that will return its IP address, rest of nodes details will be retrieved from kube-apiserver. The keepalived mode (unicast or multicast) controlled by 'ENABLE_UNICAST' environment variable, it's set by default to multicast.
