Switch from symlinks to block devices for raw block devices

[datamattsson]

This allows data protection tools to backup and restore virtual machines without having access to the host's /dev filesystem.

• Passes CSI e2e 1.34
• Backup and restore validated with OADP on OpenShift 4.19
• Depends on Switch from symlink to block devices for raw block devices common-host-libs#203 and will update this PR once merged.

@rohit-balakrishna @dileepds it seems the changes for file in common-host-libs weren't merged in the CSI driver?

The common-host-libs PR was merged and I see that the go.mod in this PR is referring to the latest commit: e9caff71ad6bf270bb5348c3eb2b5c1241689d01
Do you see any issues @datamattsson

Yes, the issue is that my PR picked up changes in common-host-libs that should already have been merged in csi-driver given that we've shipped file support already. Someone must be sitting on a branch with the shipped 3.0.0 image because it's not built from this master.
