title: remove kubernetes service-catalog finalizer with cli
body: <p>I'm trying to provision/deprovision service instance/binding from my cloud provider (IBM cloud private), Currently, there is a bug that if the service is not deprovisioned in ICP, that leaves me the orphan service instance on my ICP environment which I can't delete even with force option.
  They provide a workaround solution of:</p>
  
  <pre><code>kubectl edit ServiceInstance &lt;service-instance-name&gt;
  kubectl edit ServiceBinding &lt;service-binding-name&gt;
  </code></pre>
  
  <p>then delete the line:</p>
  
  <pre><code>...
  finalizers:
      - kubernetes-incubator/service-catalog
  ...
  </code></pre>
  
  <p>and the orphan service instance/binding will get deleted properly. I'm wondering how to automate this process with bash cli (live edit + delete line + save + exit) or any alternative way.</p>
