Adding attributes to Intent Requests

[mattrayner]

I think it would be a valuable addition to the alexs-skill-test UI to allow the specification of 'attributes' in the same way we allow for the specification of slots.

Looking at the documentation here, I wouldn't suggest automatically persisting as it says, but handling in the same way we currently handle slots

Reasoning

I'm currently developing a still that uses attributes to help manage internal state and customise the output of my intents. Currently I add attributes manually to the request JSON, but this isn't a very nice UX

Potential solution

With my limited understanding of the code base, I believe we couple duplicate the slot functionality for attributes. This would, however be a fair bit of unnecessary duplication.

Additional

I'm more than happy to work on this if you think it would be valuable and are willing to give me a bit of guidance as to where I should start?

I was just about to open this same issue.

Definitely It would be a a very useful addition to have the possibility to use attributes.

Would love to see a PR for this!
