Add Quick-Booking Workflow

Users can now quickly provision a single-host pod without having to
configure unecessary networking. This is intended to be analogous to the
workflow used during LaaS 1.0, and to speed up the process of creating a
booking for users who do not need more than a single host (for virtual
deployments)
