So we don't loose it from the original PR: #protm!

Now we removed www, FAB is not automatically set up for tests. This is causing problems in FAG provider tests.

fab provider is added as amazon's optional dependency -> that triggers the tests transitively

I was attempting to make some fixes to the pytests failing, but I am missing an idea how the previous mocked app based on appbuilder+Flask can be replicated over. I fear either we need to re-write a lot of tests or we need to add the dependency to FAB provider... which is also not helpful.
A common solution would be great but I am lagging an idea.

I think it's a matter of adding the right fixture to tests_common so that it can be used with those tests - following the new "fast_api" way of initializing the app, but I also lack a bit of understanding how it is done now without doing a lot of digging

@pierrejeambrun @bbovenzi take a look at 6a01eaa - I didn't want to tackle a general "build arbitrary url" helper, so I just did dagrun. Is there something existing for this use case though?
