I did some more digging yesterday but concluded that this is beyond my
ability to debug in a reasonable timeframe. I no longer think os-brick
is the problem though - it looks like the data passed in to os-brick is
already bad, so I think it's something in Cinder or Nova that is not
correctly handling the ipv6 iscsi address. I'm going to add both
projects to this bug and let them determine who needs to fix what.
To recap, if we bracket iscsi_ip_address then oslo.config fails to
validate the value, if we remove the brackets then cinder-volume starts
correctly and is able to create the volume, but it can't be attached to
the Nova instance. This appears to be because the iscsi port is being
appended to the ipv6 address without first bracketing the address to
separate the address and port portions (see the attached nova-compute
logs).
Here are the RDO package versions I was testing with:

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