initial commit of the OpenAI Agent POC

[birdperson1970]

This is still rought and needs a new UI field to allow the user to set their own assitant_id if you comment out:

self.assistant_id='thread_lCb2rKUzIOodcA3MZaZu61Bv'

It will create a basic assitant each time which will be really annoying to cleanup....

Going to close this PR for the same reason I mentioned in the other, but once again thank you for taking the time to push Continue forward! We're going to do something very similar to this in typescript really soon, so the idea lives on!
