Add an issue reporter which provides a more guided experience for reporting problems that is able to collect data about the user's VSCode instance. It should

• be accessible from the Help menu and command palette
• launch in a separate window
• collect the same information as the --status command, system info, workspace info, and processes
• send different data based on what type of issue is being reported
• search for duplicate issues on GitHub after user has typed a title
• allow user to remove or scrub info being sent
• integrate with upload service so users can upload logs
• on submit, preview issue on GitHub
