[FEATURE] Telemetry II - errors

[hemidactylus]

Telemetry II - error logging on client side. Ideally when a scenario goes wrong we want to send back to us: stacktrace, gitpod config, extension full version, (... other stuff?). Possible problems: 1 not all failed scenario experiences are errors in the katapod code, 2 katapod might have limited visibility into settings, etc. Hopefully VSCode API to get settings and "run-command-and-get-results" for other stuff.
