Telemetry: don't track implicitly run schematics

[StephenFluin]

• We should only track user entered commands (like schematics), not implied schematics. IE when a user runs ng new we should track that, but not the fact that they implicitly invoked ng generate workspace or ng generate project
• Aliases should be combined (ng generate c and ng generate component should be combined into a single type of GA telemetry report)
• Several of our custom metrics (at least Bundle Sizes / build times / ngOnInit) aren't being reported / I can't figure out how to see them :)
