    Wait for the BMC to complete a previously initiated reboot.

    Description of argument(s):
    start_boot_seconds  The time that the boot test started.  The format is the
                        epoch time in seconds, i.e. the number of seconds since
                        1970-01-01 00:00:00 UTC.  This value should be obtained
                        from the BMC so that it is not dependent on any kind of
                        synchronization between this machine and the target BMC
                        This will allow this program to work correctly even in
                        a simulated environment.  This value should be obtained
                        by the caller prior to initiating a reboot.  It can be
                        obtained as follows:
                        state = st.get_state(req_states=['epoch_seconds'])
    wait_state_check    By default check the state, ignore if set to False.
