{wip} [editor] add telemetry for more events

As discussed offline, we want to enable telemetry in the local editor for the following events:

- RUN_PROMPT_START
- RUN_PROMPT_CANCEL
- RUN_PROMPT_ERROR
- RUN_PROMPT_SUCCESS

This diff implements the logging telemetry for those events.

Next up will be adding "mode" to logs
