1. Proposed title of this feature request
Multi-Node Image-Based Upgrade (IBU)

2. What is the nature and description of the request?
Client requested the functionality to perform multi-node image-based upgrades (based on SNO functionality as explained in our documentation) as an approach to reduce the amount of reboots of nodes must perform during an upgrade.

3. Why does the customer need this? (List the business requirements here)
This would provide a way for skipping releases to help stay up to date with OCP release schedule since one of the main factors preventing speedy and regular upgrades is the number of reboots the nodes take during an upgrade.

4. List any affected packages or components.
