One part of the process is that we're trying to do a seamless migration from Redis to Kask using MultiwriteBagOStuff. We need to test that when the multiwrite configuration rolls out:

• existing sessions stay logged in
• logging out keeps you logged out
• logging in logs you in
• other parts of the QA script

Similarly, we need check at the boundary between the multiwrite configuation and the final configuration:

• existing sessions stay logged in
• logout and login still work
• other QA script tasks work

I think this means that we'll need to have at least some folks logged in before the configuration changes...?
