In order to attach a container to more than one network on creation the "NetworkingConfig" field is needed but the com.github.dockerjava.api.command.CreateContainerCmd does not publish the value (for potential manipulation)

The problem is that in com.github.dockerjava.core.command.CreateContainerCmdImpl#exec the value is overwritten so just providing a getter is not quite enought and the exec needs to be adapted as well
