[Needed for Discord bot] Segment Interview and Spec Generation

[ntindle]

This turns the Spec generation into the same style as the other blocks and extracts the interview stage and modifies it a bit to support a bit more of a rest style api. The codex client is now responsible for stepping through the interview phases and answering questions that come with each phase before ultimately calling generate spec

Also requires a cloud service id and interview id for Identifiers now

may want to consider seeding our users into CODEX and Cloud Services with compatible Ids and correct discords and such for core devs of the services

AGPT-400

Todo:

• swap port back or change it permanently. Collides with proxy and is a pain to run whole stack with it on 8000
• Test from /docs that it works through and through
• Make sure the spec can still happen and uses the correct details
• Update the various test systems
• Check to make sure search works
• Check to make sure that unanswered asks get answered automatically

LGTM, I hope we can follow-up on adding one test on test_api.py to prevent from us breaking this code :)
