  - Merge "Add timeout and delay time to fix the reboot problem of rt_kvm scenario"
  - Add timeout and delay time to fix the reboot problem
    of rt_kvm scenario

    JIRA: -

    The rt_kvm scenario deployment always fails on Huawei Pod2 while
    running reboot task. However it's fine on Huawei Pod1. We think
    it may be caused by the performance of Pod1. Pod1 truely has a lower
    performance than Pod2. So we add timeout and delay time to verify
    our idea.
