Epic Goal

• We need to decouple our CSI plugins so that it is possible for a user to deploy alternative implementations, or none at all.
• Package the TopoLVM plugin as a separate RPM and do not make the microshift RPM depend on it.
• Make it easy to identify the container images needed to embed MicroShift with the CSI feature in an ostree image.

Why is this important?

• The CSI controllers consume a bit of overhead. Users who are not using CSI storage likely do not want the overhead.

Scenarios

1. A user deploys MicroShift with the CSI snapshot controllers and their own CSI driver.
2. A user deploys MicroShift with the CSI snapshot controllers and the LVMS driver.
3. A user deploys MicroShift without CSI or CSI snapshot.
4. A user deploys MicroShift with LVMS for CSI, but no snapshot controllers.
5. A user deploys MicroShift with CSI snapshot with all container images embedded in their OS image.
