add parameter continue_on_fail

v1->v2:
Discard previous implementation, take a direct and simpler method.

By adding pamameter 'continue_on_fail=initqueue|mount_root', user can decide if continue after these points timeout. And can extend to other delay or loop point later if needed.

Baoquan He (2):
Add parameter continue_on_fail to make dracut continue after
initqueue timeout
Continue when mount rootfs failed by specifing
'continue_on_fail=mount_root'
