Design summary:
Add a feature to swarming's pool.cfg configuration to allow the association of a 'task template' (specifying e.g. CIPD packages, envvars, etc.) with a swarming pool. New tasks created in the pool will adopt the task template as a base, and then be merged on top of the template, before calculating the task hash and scheduling it.
