Thanks everybody for your help.

I'm going to mark this SOLVED but unexplained.

When I had everything the way I wanted it I turned on NetworkManager and 
did a systemctl restart network, then reboot.  Lo and behold, the 
bridges were up.  Systemctl disable NetworkManager, then reboot. Bridges 
were up.

Apparently NetworkManager leaves a footprint somewhere that affects 
whether or not the bridges are brought up.
