Trigger AI updates via an API

When I crate a draft via an API request (/v1/drafts/) I get this response:

'id''status''html''num_tweets''last_edited''scheduled_date''published_on''share_url''twitter_url''linkedin_url''text_first_tweet''html_first_tweet''text_preview_linkedin'

I propose a new PUT API endpoint (/v1/ai/), which will take the following data:

id: 123,fix-type: "fix-grammar"

and will update a single tweet, based on the data.

This will probably also require the draft endpoint to return id of each tweet in the thread.
