Add a way to query BIOS DMI in csi-proxy

[ddebroy]

What happened:
To support CSI plugins like vsphere, csi-proxy needs to be able to surface BIOS DMI details to the plugin. Please enable this support, potentially through a new system API group. This should do something identical to: https://github.com/kubernetes/kubernetes/blob/103e926604de6f79161b78af3e792d0ed282bc06/staging/src/k8s.io/legacy-cloud-providers/vsphere/vsphere_util_windows.go#L29

What you expected to happen:
There is no way to surface BIOS DMI details today.

How to reproduce it:

Anything else we need to know?:

Environment:

• CSI Driver version: NA
• Kubernetes version (use kubectl version): NA
• OS (e.g. from /etc/os-release): Windows
• Kernel (e.g. uname -a): NA
• Install tools:
• Others:

#81 addressing this

[rhockenbury]

It looks like #81 was merged so this issue can likely be closed.

Do you know if there has been any progress on supporting vsphere CSI with csi-proxy?
