title: Set verify_certs=False yet elasticsearch.Elasticsearch throws SSL error for certificate verify failed
body: <p>self.host="KibanaProxy"</p>
  
  <p>self.Port="443"</p>
  
  <p>self.user="test"</p>
  
  <p>self.password="test"</p>
  
  <p>I need to suppress certificate validation. It works with curl when using option <code>-k</code> on command line. But while connecting using elasticsearch.Elasticsearch from Elasticsearch python module, it throws error.</p>
  
  <p><code>_es2 = Elasticsearch([self.host], port=self.port, scheme="https", http_auth=(self.user, self.password), use_ssl=True, verify_certs=False)</code></p>
  
  <p><code>_es2.info()</code></p>
  
  <p>Error:</p>
  
  <pre><code>    raise SSLError('N/A', str(e), e)
  elasticsearch.exceptions.SSLError: ConnectionError([SSL: CERTIFICATE_VERIFY_FAILED] 
  certificate verify failed (_ssl.c:590)) caused by: SSLError([SSL: 
  CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590))```
