ENH: Fix CLI progress bar setup

The progress bar was only initialized on setDefaultValue when it should be
initialized everytime a new command line module node is selected.

See Issue #2988
ENH: Add VisibleAfterExecution option for CLI Progress bar

This option defines if the progress bard stay visible at the end of the
execution of the CLI or not.

See Issue #2988
STYLE: Align CLI Progress bar "Status:" label to the right

It is better for the "Status:" label to be closer to the current status.
Otherwise the user just glances over it without really noticing the
relation between both.

See Issue #2988
