   When marking a failed task as success in Graph View, this PR gives the user 
an additional checkbox "Resume". When checked, this option automatically clears 
downstream tasks that were blocked by the failed task after marking it success.
   
   For example, given a DagRun currently in this state, with ``run_after_loop`` 
and ``run_this_last`` blocked by the failed task ``runme_1``:

   When the user marks ``runme_1`` as success with "Resume" checked, downstream 
tasks in ``upstream_failed`` state are automatically cleared:

   The DagRun looks like this after clicking OK:
