title: delete one level in a python dict keeping the values
body: <p>I have the following python dictionary:</p>
  
  <pre><code>'load_balancers': {'App': {'DJMatcher': {'security_group': 'sg-618d1c05', 'service_name': 'djmatcher/svc', 'certificateId': 'net', 'health_check_path': '/djmatcherstatus/ma.html', 'DNS': {'fde': {'record_name': 'platform-enrichment-djmatcher', 'ttl': 60}}}}}
  </code></pre>
  
  <p>Now it basically represents the following YAML:</p>
  
  <pre><code> LoadBalancers:
      App:
          DJMatcher:
              certificateId: 'net'
              health_check_path: /djmatcherstatus/ma.html
              security_group: *svc_sg1
              service_name: *sn
              DNS:
                  fde:
                      record_name: platform-enrichment-djmatcher
                      ttl: 60
  </code></pre>
  
  <p>I want to remove the second level of key - "App" and keep the rest as it is, which means the resulting python dictionary should become this where I delete the key App but the value now becomes the value for its parent key "load_balancers" :</p>
  
  <pre><code>'load_balancers': {'DJMatcher': {'security_group': 'sg-618d1c05', 'service_name': 'djmatcher/svc', 'certificateId': 'net', 'health_check_path': '/djmatcherstatus/ma.html', 'DNS': {'fde': {'record_name': 'platform-enrichment-djmatcher', 'ttl': 60}}}}
  </code></pre>
  
  <p>Any good way to achieve this ?</p>
