[LTP] [RFC] ltp test add reboot function

[Cixi Geng]

Thanks for you experiences on the reboot，
So far my opinion is add a reboot service by chkconfig or something like that.
the service will start runltp scripts from last break off point.
when the tst_test have .tst_needs_reboot =1 flag, it wil strore the
run status and
reboot the machine before run the test case.
Now I want to know what needs to be preserved？
