feature: add support for ood

Open On-Demand provides a web gateway to cluster with support for terminal, desktop and file access via the browser. This feature is focused on instantiating an ood web gateway node for the provisioned ohpc cluster and making it the default interface for the cluster.

The initial work is to provide vagrant and ansible tooling to provision the node and integrate it with the Xsede basic cluster. Early work for this feature exists in a fork of the vagrantcluster codebase providing a foundation for getting vanilla ood running on a node via ansible.

This work effort will integrate this with the XCBC code base and associated cluster.
