1. Make Rootless and Systemd flags part of config.Cgroups. 2. Make all cgroup managers (not just fs2) return error (so it can do more initialization -- added by the following commits). 3. Replace complicated cgroup manager instantiation in factory_linux by a single (and simple) libcontainer/cgroups/manager.New() function. 4. getUnifiedPath is simplified to check that only a single path is supplied (rather than checking that other paths, if supplied, are the same).
