Allow variables in notify list

This promotes reuse of a generic service tasks and handlers list, since a significant amount of services are used the same way.

Can you give an example of this being used in a playbook? I'm not sure I follow how this makes things reusable.

A lot of my services use the same basic format, install service, template configuration file, and enable the service, restarting it if the configuration file changes. So I have a tasks/templated-service.yml that I include for each of them:
---
- name: install $service
action: yum pkg=$package state=latest
notify:
- restart $service
- name: install $service configuration
action: template src=templates/$service.conf dest=$dest owner=$owner group=$group mode=$mode
notify:
- restart $service
- name: enable $service
action: service name=$service state=started enabled=yes

and then in the playbook I just use
tasks:
- include: tasks/templated-service.yml service=radvd package=radvd dest=/etc/radvd.conf owner=root group=root mode=0644
handlers:
- include: handlers/service.yml service=radvd

Sounds reasonable, merged, thanks!
