STs seem to be broken on newer docker releases

[fasaxc]

I tried to run cd calico_node; make st on my dev machine. I see errors in the console from docker.

Expected Behavior

Clean ST run.

Current Behavior

docker exec -it host1 sh -c 'docker network create --driver calico --ipam-driver calico-ipam  testnet1'
  # Return code: 1
  # Error response from daemon: legacy plugin: plugin not found
  # 

Possible Solution

Looks like a change to the docker API has broken the STs?

Steps to Reproduce (for bugs)

1. cd calico_node
2. make st ST_TO_RUN=tests/st/policy/test_profile.py

Context

This is blocking development of STs for the feature I'm working on.
