I feel partly involved into the slowdown so I'd like to get some 
guidance over the issue.

Take as an example the following, it is going to create two volume 
snapshots (one per test):

https://review.openstack.org/#/c/28176/

The tests share an origin volume created by setUpClass but repeat the 
snap creation step.

Creating the snap is the purpose of one of the tests indeed, while the 
second is attempting to create a snap-based volume, essentially 
repeating the initial snapshot creation as one of the steps.

One could speed up things by moving also the snapshot creation in the 
setUpClass but, from my pov, creating a snapshot successfully is what we 
want to test, not just a setup step.

So, what shoul be the right approach in such a situation?

Also, in relation to the gating issue, should a _slow_ test like this be 
part of the gating or shouldn't it? It's slow but can we run the gating 
without checking if one is still able to create a volume snapshot?

How about splitting this per component? I'd volunteer for the volume 
tests. Adding the import should be an easy task, picking up the right 
tests for taking would be a separate commit as I expect a number of new 
suggestions in the review comments. Makes sense?
