Errors in some of the recently added examples

[miguelgrinberg]

While working on testing the request converter I have found that some of the examples that were added recently have errors.

• ClusterPutComponentTemplate1
  The template parameter should not be null, the settings and mappings parameters are not accepted by the server.

• indicesPutTemplateRequestExample1
  The properties parameter is not accepted by the server.

• ReloadSearchAnalyzersRequestExample1
  This GET request does not accept a body, the arguments should be passed in the query string.

• UpdateTransformRequestExample1
  The pivot parameter is not accepted by the server.
