    Adds garp_master_repeat and garp_master_refresh to keepalived.conf

    This patch aims to solve an issue when, in some cases, the L3 agent might
    start before the OVS agent during a node boot process.
    At such scenario, the L3 agent will configure the routers before the OVS agent
    done syncing with the server and starts processing ovsdb monitor updates.

    The result:
    1. L3 agent finishes configuring an HA router
    2. Keepalived spawned
    3. In case of transition to master state, it (keepalived) sends gratuitous ARPs
                                                                ^---The issue
    4. The OVS agent has just finished plugging its ports

    Meaning, the gratuitous ARP will be lost, but the router acting as master.
