Support for new Actions assistants

[andrewrfreed]

Need to update tool or confirm it works well for Action-based assistants, not just Dialog-based.

Many customers use this library of python functions inside notebooks that extract conversation logs and perform various analytics on the extracted log data. None of those customers are going to move to the New Watson Assistant until these functions work with the New WA. I can provide specific customer names if needed. This issue should have a high priority.

I agree, we don't have actions in sight

@leighawilliamson @kevin2107 please note both capabilities (logs #227 and blind test #224 ) are addressed, see linked pull requests.

Thanks to many for review and help especially @lmazzoli who helped drive logs to completion.
