Potential changes to Rules for AI Triage Service

[jeo02]

Using this PR to discuss changes to the AI Label Service to include AI comments. Changes mainly surround the response structure, and how we react to the new fields.

{
    "labels" : string[],  // zero or two
    "suggestion" : string | null,  // never empty
    "solution" : string | null  // never empty
}

Suggested change

	"suggestion" : string | null,
	"solution" : string | null
	"suggestion" : null,
	"solution" : null

I'd suggest that we break this out into the 4 possible states with examples for each:

• Manual triage needed. (empty labels, no suggestions, no solution)
• Label prediction made for triage. (labels populated, no suggestion, no solution)
• Label prediction with suggestion (labels populated, suggestion populated, no solution)
• Label prediction with solution (labels populated, no suggestion, solution populated)
