    [Fullstack] Change time waiting for async ping results

    During agents restart there is async ping run and there is
    called function to wait until all async ping workers will
    finish their job.

    In TestHAL3Agent.test_ha_router_restart_agents_no_packet_lost
    there are 60 pings sent with 1 second timeout so default
    wait_until_true timeout which is set to 60 seconds might not
    be enough in some cases.
    Because of that wait_until_true timeout is now set as
    twice higher value than is needed to number of packets to send
    with ping_timeout.

    This should give enough time to finish all workers.
