Ticket: CM-10088

When we pulled this patch from upstream there was one spot where we
incorrectly used min_ls_interval (5s) instead of min_ls_arrival (1s).

    configuration options for faster OSPF convergence

    Allow configuration of faster OSPF convergence via the
    min_ls_interval and min_ls_arrival timer lengths.

    This patch was originated by Michael, and cross-ported
    to Cumulus's Quagga.
