Set the default help mode to options #5182

The default help mode is currently set to 'full', which means that a lot of text is printed if the user makes a mistake running the command, or requires help on purpose. In both scenarios it provides better UX if the help mode is short by default. The user can always extend it to full if so required.

Implementation

• Change the default help mode to 'options'

Moved out of scope

• Take care that the printed help in case of errors only shows the description of the command, combined with a message about how to get the full version.
