csi: handle spec updates for volume health

Description

The condition of a volume is no longer reported within the status information returned in the list volume response. Instead, an endpoint now exists to query the volume health. The new endpoint is now used to include the condition of the volume if it is available.

Like the previous volume condition field, the volume health endpoint is considered alpha within the spec and may be removed or modified in the future.
