    Detect and kill hung vim process

    There is a specific scenario when vim starts where threads keep
    stalled and then after 600s the subsystems are marked as not sane.
    In this situation vim is supposed to quit, but instead it stays
    alive but in a failed state.

    This commit adds an extra step in vim monitoring ocf script to
    test if vim rpc port is open and responding, and if not, vim
    is forcefully killed.

    Test Plan
    PASS: install/bootstrap/unlock AIO-SX
    PASS: get vim to a not-sane state and observe it being killed
          and restarted in this scenario
