    Fix LVM IPv6 target portals
    
    The LVM driver is reporting incorrect target_portal and target_portals
    entries for IPv6 with all the targets, as it is not enclosing the
    address in square brackets making it impossible for iscsiadm in OS-Brick
    to tell the port appart from the IP address.
    
    This patch makes sure that IPv6 addresses in target_portal and
    target_portals are properly formatted in the [IPv6_address]:port when
    the IPv6_address does not already include the square brackets.
    
    This fix affects all the targets: IET, LIO, TGT, CXT, and SCST.

  The problem appears to be that we bracket the value.  If I remove the
  brackets then cinder volume works correctly.
