Duplicate CBT state to storage view

[TristisOris]

Is your feature request related to a problem? Please describe.

It's no way now to find wher CBT is enabled, or maybe i want to enable it everywhere.

xo-cli also search nothing:
vdi.set id=<string> [name_label=<string>] [name_description=<string>] [size=<integer|string>] [cbt=<boolean>]
vdi.set cbt=true

Describe the solution you'd like
Mirror disk settings from VM to storage view.
