Bump csi versions

[kschumy]

Rationale

We currently use Go 1.15 for all the CSI sidecar. We should be using a new version of Go for them and need to update the sidecar versions to ones that use an updated version of Go.

CSI external-snapshotter was NOT updated at this time. See below for explanation.

Description of changes

external-attacher

• Bumped version from 3.1.0 to 3.2.0. Based on the README and supported versions table, 3.2.0 is compatible with Kubernetes 1.17 and newer.
• Bumped Go version, as it uses Go 1.16
• Added README

external-provisioner

• Bumped version from 2.1.1 to 2.2.2. Based on the README and supported versions table, 2.2.2 is compatible with Kubernetes 1.17 and newer.
• Bumped Go version, as it uses Go 1.16

external-resizer

• Bumped version from 1.1.0 to 1.2.0. Based on the README and supported versions table, 2.2.2 is compatible with Kubernetes 1.16 and newer.
• Bumped Go version, as it uses Go 1.16
• Added README

external-snapshotter

• Added README
• !!! IMPORTANT !!!!
  The version (v3.0.3) was NOT changed. The Go version is bumped to 1.16 in v4.1.0. The supported version table says we're at the highest compatible version for 1.18 and 1.19. Since they are incompatible with v4.1.0, we have no way of getting a newer Go version simply by bumping version.
