Fixed illegal argument exception in indices.py as request_timeout is expected instead of timeout. (#937)

The `timeout` parameter in docstring is misleading for following methods in elasticsearch.client.indices.py, renamed this param in query_params decorator and docstring to `request_timeout`:

1. create
2. open
3. close
4. delete
5. put_mapping
6. put_alias
7. update_aliases
8. delete_alias
9. put_template
10. delete_template
11. shrink
12. rollover
