Support Predeployed Overcloud Servers

[LukeShortCloud]

As far as I can tell, InfraRed does not have full support for helping setup predeployed/preprovisioned nodes. This can greatly speed up deployment time and lowers the complexity by skipping the Ironic provisioning entirely.

This entails:

• Enabling TripleO/RHOSP repositories on the Overcloud nodes.
• Installing and setting up os-collect-config for Heat on the Overcloud nodes (only for non-config-download deployments).
• Keying the stack user from the Undercloud to access a sudo-privileged user on the Overcloud nodes. It can be keyed to any user but the documentation suggests stack.
• Using predeployed server Heat templates.

As part of this journey, I am trying to add a --images-task none argument to the tripleo-undercloud plugin. I have a branch up to test this: https://github.com/ekultails/infrared/tree/undercloud_images_task_none
