Add the possibility to switch between last eligible & last run

# Add the possibility to switch between last eligible & last run

## Context

For now, the default displayed execution is the latest version analysed successfully by ARA (even if this version doesn't meet the threshold and is not eligible).

For example, if the latest version analysed successfully by ARA was made 2 days ago, users will see it on the main page, and can believe that it's the "latest version", even if a new version was made 1 day ago (or today) and is not displayed because it was discarded.

## Expected

Add a switch button to the top of the ARA executions view to display either the last analysed executions on all the exec (develop, stab, master) or the last run executions (which will includes the discarded ones).


Add a setting in the project to choose the default display mode.

(Replace "Eligible" by "Analysis" in the mockups above)

Start in the ARA executions view and project settings, locating how the displayed execution is selected and where the default project display mode is stored. The work is complete when users can switch between the last eligible analysis and last run, including discarded runs, and choose the default mode in project settings.
