    Apply haproxy vars to haproxy group instead of haproxy_all

    Any ansible command loads the group vars/host vars.
    If haproxy group isn't properly loaded with hosts, the whole
    group_vars/haproxy_all/keepalived.yml will fail to get an index
    for any host belonging to the group.

    Instead the index should search in the group in which the variable
    applies to, to ensure it's always the same kind of group.

    In a later commit, we should make sure the index is always done when
    group size is bigger than 0.
