title: Skip failed steps in kubeflow pipeline and continue the pipeline
body: <p>Does anyone have an example how to handle failed steps in pipeline and continue pipeline even after failed step. ExitHandler can execute only the one, last step while I need to catch any possible failure i.e. something more like (pseudocode)</p>
  <pre class="lang-py prettyprint-override"><code>step1 = comp_op1()
  with dsl.Condition(even if step 1 failed)
   step2 = comp_op2()
   with dsl.Condition(even if step 2 failed)
     step3 = comp_op3()
  </code></pre>
  <p>Any idea?</p>
