Title:
  please mark a volume as read-only

Status in OpenStack Dashboard (Horizon):
  Won't Fix
Status in python-cinderclient:
  Won't Fix

Bug description:
  currently, once I update a volume to read-only its only shown in the metadata. 
  however, I think a read-only change (could be worse when we change from read-only to read/write) is really important and should be very visible to the user. 

  as you can see, we can only see that the volume is read-only in the
  metadata:
