Issue MESOS-5130: Enable `newtork/cni` isolator in `MesosContainerizer` as the default `network` isolator.
Currently there are no default `network` isolators for `MesosContainerizer`. With the development of the `network/cni` isolator we have an interface to run Mesos on multitude of IP networks. Given that its based on an open standard (the CNI spec) which is gathering a lot of traction from vendors (calico, weave, coreOS) and already works on some default networks (bridge, ipvlan, macvlan) it makes sense to make it as the default network isolator.
