Telemetry for improperly zipped apps

[satvu]

Follow up of this issue. We've been seeing an increase in "No Job Functions Found" errors as a result of improperly zipped apps that resulted in an unexpected folder structure.

While these apps have the correct files needed to start up (like host.json), the incorrect folder and file structure can lead to vague errors that prevent the apps from behaving as expected. Some considerations for tracking this:

• Track guaranteed failure cases (double-zipping an app, similar to issue linked above)
  • Runtime languages have different payloads, need to avoid throwing errors for valid apps
• Logging (minimal) file structure to help with servicing and debugging this error
• Design error/failure behavior for improperly zipped apps, troubleshooting guides
