bootstrap issue with docker bridge

[josefwells]

Problem: when using a self-defined docker bridge as I suggest here, if that bridge is in your initial nftables rules, nftables will fail because that bridge device doesnt exist.

Solutions:
Get good at systemd and start a docker service to initialize the bridge device BEFORE nftables tries to come up.
or
Create the interface outside of docker and point docker to that interface. Research indicates this is less likely to work, I'll dig up the docker ticket# if i run into too much trouble with solution 1.
