Hi all,

the removal of the Sahara tests from Tempest [1] broke the tests now in 
sahara-tests, and basically I underestimated the fall-out of the removal. 
Apart from a minor issue due to the wrong exception [2], the key issue comes 
from the option groups in tempest.conf, which are defined as data-processing 
and data-processing-feature-available, while the code tries to access 
CONF.data_processing. Previously this was handled by some magic mapping [3], 
which can't be used, as it is, by plugins.
I came up with this solution [4] after discussing with Andrea Frittoli. The 
patches only fails with the automation negative tests, which are on the way of 
the Dodo anyway [5].
The alternative fix for sahara would involve patching the configured 
tempest.conf in few branches, in addition to the fixes to sahara-tests, and 
I'd frankly prefer a more general solution.

My question is: can you please approve [5] and [4], so that Sahara gates can 
be unlocked?
