ACI : display exposed port/IP

[gtardif]

when running docker run nginx -p 80:80, subsequent docker ps should display a PORTS column with the ACI public IP & port where we can connect to the deployed app.
(Code can be taken from /docker/spiky)

for ports parsing, we can use https://github.com/docker/go-connections
