    Make update status dialog less confusing

    Now, we give the init status of the volume when resetting status.
    The first glance is the current status, instead of "Select an
    new status", and we could do nothing with the status will confuse user.
    The same with snapshot.

    According to the above situation and Akihiro's suggestion:
     - Use "Select on new status" as the default label
     - List all possible values for status *including the current status*
     - Add "(current)" to the current value in the dropdown list
