When create a docker container without --net option, the NetworkMode is default
when using bridge mode, then the docker containerizer will construct a string
{{"NetworkSettings.Networks." + NetworkMode + ".IPAddress}} as the
addressLocation for the container, but this is not true as the actual address
location is {{NetworkSettings.Networks.bridge.IPAddress}}.
The mesos do not support {{default}} network for now, but once we introduced
the user defined network, this will be a problem cause we cannot get the exact
IP address for the container when using docker containizer.
