currently, the Ansible plugin is limited to execute Ansible roles. However,
there are several reasons for considering direct Ansible playbook
execution.
Just with roles, there is a lack of control over the execution order as the
structuring element, the playbook, is statically created by the plugin. In
addition to that, some fundamental features of Ansible on playbook-level
cannot be used with roles, for example strategies
<http://docs.ansible.com/ansible/playbooks_delegation.html#rolling-update-batch-size>
.
Therefore, I think, that the plugin should support playbook execution, not
just role execution.
What do you think about this? I would really appreciate some more thoughts
before starting to work on this.

Dependencies and ordering with roles can be accomplished at the role
level (not via Foreman) - check

I'm afraid it's an area where the project clashes with Ansible Tower
quite a lot. To be fair I think playbooks would fit better as another
provider for Foreman remote execution model. Unfortunately I couldn't
finish the provider, but it worked (for my dev usecase )
Actually, I am also working with role dependencies at the moment, which is
fine for the time being for structuring a play. The new plugin feature of
running roles against hostgroups reduced the need for me to run playbooks
directly. However, it's a bit of a pity that all the playbook-level
features of Ansible like serial execution cannot be used at the moment. I
suppose, we can leave it with just roles for now but maybe we need to find
some ways in order to be able to make use of the playbook-level Ansible
features if required.
