Toolkit Annotation support

The toolkit should support first class support for adding annotations

export function addAnnotation(annotation: Annotation): void 

Annotation object will match this

Annotation level will be a toolkit enum which gets written as a string to the annotation. We need to add Notice to the timeline issue

export enum AnnotationLevel {
  Notice = 0,
  Warning = 1,
  Failure=2
}

the equivalent cmd will accept properties that match the annotation properties

echo ::add-annotation annotation_level=error, path=css/main.css, start_line=0, end_line=0::myMessage

toolkit error and warning will emit [error]message and [warning]message which the UI will decorate red or yellow. (error and warning does not currently support an annotation). The web UI should colorize but string the [error] and [warning] from the view (but still in the logs)

The existing logging error and warning command will emit [error]message and [warning]message. Even though not documented, they take properties (problem matchers). If those properties are used, then for compat, create an issue object which will become an annotation service side.

After this is complete, change problem matchers to use the add-annotation cmd or toolkit methods.
