Mark Goddard 3c02c966cb Performance: remove one include_tasks in nova-cell 
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.
