--------------------------------------------------------
This is because network/cni isolator requires linux launcher, and linux
launcher requires freezer.
We enable network/cni isolator by default on linux if not specified, that means
on any linux that do not have freezer support, agent will fail to start.
I think we should check the availability of the linux launcher before enabling
network/cni isolator.

>
> With the network CNI isolator, agent now _requires_ cgroups to be installed
> on the system. Can we add some check(s) to either automatically disable CNI
> module if cgroup hierarchies are not available or ask the user to
> install/enable cgroup hierarchies.
> On CentOS 6, cgroup tools aren't installed by default.
