FAST: configuration switches for features

[ludoo]

This shows how I would approach the topic of "configuration switches" we discussed last week:

• a simple object variable with one bool type member for each feature
• declared in stage 00 and set by default to enable all features
• stored in globals like other user-configurable stage 00 variables that carry over to other stages

It looks pretty simple and does not complicate code readability.

Very nice!

I'm aware this is just a stab - couple of observations:

• Disabling branches has impact also on later stages (definitely networking)
• I would want to see e2e tests with disabled features

Nice one.

• Disabling branches has impact also on later stages (definitely networking)

Yep, the config is trickled down through all stages, so each stage should comply with it for it's own part.

• I would want to see e2e tests with disabled features

Yep, we need to great point.
