Ensure our chatobot samples work in environment where a secure connection is required

[iocanel]

Tried some samples inside OpeShift and exposed them as routes. The chatbot didn't work as expected as it uses ws and a secure connection was required in this case.

What worked for me is changing the protocol from ws to wss and fallback to ws. if wss is not available.

I think this needs to be applied to all our samples.
