Temporarily to remove stable compat jobs on taskflow
Temporarily to remove stable compat jobs on taskflow

To unwedge the gate on stable we need to temporarily remove the
icehouse jobs because a new ceilometer tests is failing at too high a
rate to let any unwedging fixes through. This should be reverted soon
after things are unwedged.
