Generate Pre/Post Puppet Tasks for all roles

Generate Pre/Post Puppet Tasks for all roles

We need to generate the Pre and Post Puppet Tasks for all roles, not
just the Controller role. Otherwise, you have to have a role
specifically named Controller that is running your pacemaker services,
or pacemaker won't be properly handled on stack-updates.

When using deployed-server's it's actually not possible to have a role
called Controller, since we need to use all custom roles so that we can
set disable_contraints on each role. Further, it is not possible to
redefine the Controller role since puppet/controller-role.yaml is listed
in the excludes file.
