Overcloud Controller deployments fail due to not being able to resolve the value of keystone::wsgi::apache::workers. The variable fails to get expanded on the Overcloud Controller node.
Specifying a literal integer value (e.g. 11) in the Template or Plan instead of the default variable of %{::processorcount} produces a successful deployment.

I've also seen this (deploying master from the UI), setting Priority to High as it makes the deployment fail. (It's also not obvious to debug, with the error focusing on trusted_cas).
