Disable AngryChef builds and promotions
Disable AngryChef builds and promotions

Releng has decided it's best to stop building/promoting AngryChef right
alongside Chef for a number of reasons:

* Increases the fragility of the pipeline and requires a Chef build to
  pass on the already large platform matrix times 2.
* AngryChef builds will not be required in our new Buildkite based
  pipeline as Chef is not used to manage the underlying instances in the
  elastic queues.

We just built/promoted AngryChef 15.0.293 out of band and will continue
to do this if future AngryChef builds are required.
