Summary
This adds NodeStage to the internal/minimal EBS CSI Driver. This code comes directly from https://github.com/kubernetes-sigs/aws-ebs-csi-driver and is used to create a minimal Node-specific driver.
Implementation details
The driver is updated to use the public.ecr.aws/eks-distro-build-tooling/eks-distro-minimal-base-csi-ebs base image which contains all requisite mount utilities in the path while still keeping the overall driver to ~50mb in size. The NodeStage implementation adds only the files and dependencies which are directly tied to the EBS volume Mount/format/fs resize.
Testing
Manual test process:
New tests cover the changes: no
Description for the changelog
