Call to Conversation service returns SSLError [Pepper example]

[arlemi]

When using the Speech to Text and Conversation example for the Pepper robot, the call to the Conversation services returns the following error:
SSLError: [Errno 1] _ssl.c:504: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

This can be bypassed by adding verify=False in the request.post call but this is not recommended as it is also highly insecure.
