Including tasks has a performance penalty when compared with importing tasks. The nova-cell role uses include_tasks twice when generating certificates and keys for libvirt TLS. While a dynamic include makes sense here for a non-default feature, we can use one include rather than two with the same effect. Since this task runs against compute nodes the overhead is significant. See [1] for benchmarks of include_tasks and import_tasks.
