    Restart tiller on openstack pending install check

    This is another attempt at fixing the same bug as the merged review
    https://review.opendev.org/c/starlingx/config/+/783472 had tried, since
    there were reports indicating that the bug would still occur on certain
    setups.

    This patch explicitly forces a tiller restart when catching the first
    HelmTillerFailure exception caused by the broken pipe error, instead of
    only trying to rerun the 'helm list' command, which was believed to be
    a reliable workaround to the problem, but didn't solve it in every
    possible scenario.
