Sean Dague 8400d7a184 Revert "Revert zuul status in gerrit"
This reverts commit ff6d73b989.

This brings back zuul inline status which is further optimized in
follow on patches. We do this in phases because it's a lot easier to
review that way.

It also introduces zuul_inline global control variable, so we can land
this turned off, and enable in the debugger to verify it's doing the
correct thing.
