Open Stack

   But, Mousie, thou art no thy-lane,
   In proving foresight may be vain;
   The best-laid schemes o' mice an' men
   Gang aft agley,
   An' lea'e us nought but grief an' pain,
   For promis'd joy!
     - To a Mouse, Rabbie Burns, 1785

We have awoken this fine morning to find ourselves having two different 
devstack-gate issues[1][2] that are related neither to each other, nor 
to Zuul v3 itself (although one of them only surfaces in Zuul v3)

Given the typically long iteration time on working through base 
devstack-gate issues, it seems rather imprudent to flip the v3 switch 
until they are sorted.

Consider the rollout on hold until the devstack-gate issues are sorted. 
We'll follow up when we it's a go again.

Thanks!
Monty

[1] Ownership of the in-image artifact cache. Has a patch working 
through the gate now: https://review.openstack.org/#/c/511260/

[2] Issue with our Ubuntu mirrors being out of sync causing package 
version conflicts between mainline and UCA mirrors. Root cause and 
solutions are being worked.
