Display each command as a collapsable section under CI (#2976)

* add logging wrappers for ci services

* add section_title to console theme

* Import main console instance

LOGGING_CONSOLE prints to stderr. The CI docs did not say anything about
reading from stderr, so using it for this is questionable.
For now, just use the main console instance.

* always return from func
