Performance: use import_tasks for register and bootstrap Including tasks has a performance penalty when compared with importing tasks. If the include has a condition associated with it, then the overhead of the include may be lower than the overhead of skipping all imported tasks. In the case of the register.yml and bootstrap.yml includes, all of the tasks in the included file use run_once: True. The run_once flag improves performance at scale drastically, so importing these tasks unconditionally will have a lower overhead than a conditional include task. It therefore makes sense to switch to use import_tasks there. See [1] for benchmarks of run_once.

Performance: replace unconditional include_tasks with import_tasks Including tasks has a performance penalty when compared with importing tasks. If the include has a condition associated with it, then the overhead of the include may be lower than the overhead of skipping all imported tasks. For unconditionally included tasks, switching to import_tasks provides a clear benefit. Benchmarking of include vs. import is available at [1]. This change switches from include_tasks to import_tasks where there is no condition applied to the include.

Performance: optimize genconfig Config plays do not need to check containers. This avoids skipping tasks during the genconfig action. Ironic and Glance rolling upgrades are handled specially. Swift and Bifrost do not use the handlers at all.
