title: upgrade to DSE 4.6 endpoint_snitch issue
body: <p>I am testing upgrading to 4.6, and there seems to be a change in the snitch. 4.5 ran fine with.</p>
  
  <pre><code>endpoint_snitch: com.datastax.bdp.snitch.DseDelegateSnitch
  </code></pre>
  
  <p>Configured in the cassandra.yaml file, but 4.6 fails to start.  The only way I can get it to start is to use one of the classic snitches, but then I have to configure my Datacenter names and such... How do I use the DseDelegateSnitch.</p>
  
  <p>I am getting the following error with the above config when I use the DseDelegateSnitch.</p>
  
  <pre><code>Fatal configuration error
  org.apache.cassandra.exceptions.ConfigurationException: DseDelegateSnitch is now handled automatically; please set endpoint_snitch in cassandra.yaml to any valid IEndpointSnitch (probably whatever is configured for delegated_snitch in dse.yaml).  Also remove delegated_snitch from dse.yaml if it is still set there.

  <p>The node will start when I use a snitch such as propertyfilesnitch.</p>
  
  <p>Thanks in advance.</p>
  
  <p><strong>Update on solution</strong></p>
  
  <p>I did not have the delegate snitch in the dse.yaml file, but I did have DseDelegateSnitch in cassandra.yaml.  I ran this:</p>
  
  <pre><code>sed -r 's/DseDelegateSnitch/DseSimpleSnitch/g' /etc/dse/cassandra/cassandra.yaml
  </code></pre>
  
  <p>And I am back in business.</p>
