Insights/critical insights telemetry

Created by: coury-clark

Implements RFC 584 to add the totalCount for Code Insights to critical pings. This will be used for licensing enforcement. This separates into a new object codeInsightsCriticalTelemetry to avoid any name collisions and add support for future changes to this license enforcement strategy.
