OOD installation from running a standalone ood role fails because of lua-posix dependency.

[eesaanatluri]

Error:

    openstack.image:   ood failed | msg: Error: Package: ondemand-2.0.27-1.el7.x86_64 (ondemand-web)
    openstack.image:            Requires: lua-posix

Description: The role ood errored out as it could not satisfy installing the dependency lua-posix which is part of epel-release. This task is part of the prep_ood which we don't run in ood-packer.yaml. prep-ood is part of the playbook targeted for ohpc based dev cluster.

Proposed Solution:

• Add task to install epel-release in ood role so that it is self-sufficient
