Steps taken to update to CSI v1.10.0:

1. Updated github.com/container-storage-interface/spec version in go.mod.
2. Ran go mod tidy
3. Ran go mod vendor
4. Installed mockgen to my PATH with go install github.com/golang/mock/[email protected]
5. Ran go generate in the driver directory.
6. Applied the fix from bump CSI spec to v1.10.0 #519 (added csi.Unsafe*** interfaces where necessary in driver and test).

Then I added the SnapshotMetadata interface to the following files in driver:

• driver-controller.go
• driver.go
• mock.go
