docs: Convenient method for adding a context environment to the embedded Tomcat. Creates
  a <code>ContextEnvironment</code> object and adds it to the list of the context
  environments.
  
  <p>
  Example:<br>
  Tomcat context xml file
  
  <pre>
  &lt;Environment name="aparam"
  value="test"
  type="java.lang.String"
  override="false"/&gt;
  </pre>
  
  Programmatic way:
  
  <pre>
  embeddedTomcat.addContextEnvironment(&quot;aparam&quot;, &quot;test&quot;, &quot;java.lang.String&quot;);
  </pre>
  
  @param name name of the context environment
  @param value value of the context environment
  @param type type of the context environment
  @return The embedded Tomcat
