Use fs cgroups by default

Browse Source 
Our implementation of systemd cgroups is mixture of systemd api and
plain filesystem api. It's hard to keep it up to date with systemd and
it already contains some nasty bugs with new versions. Ideally it should
be replaced with some daemon flag which will allow to set parent systemd
slice.

@ -452,11 +452,11 @@ single `native.cgroupdriver` option is available.
The `native.cgroupdriver` option specifies the management of the container's
cgroups. You can specify `cgroupfs` or `systemd`. If you specify `systemd` and
it is not available, the system uses `cgroupfs`. By default, if no option is
specified, the execdriver first tries `systemd` and falls back to `cgroupfs`.
This example sets the execdriver to `cgroupfs`:
it is not available, the system uses `cgroupfs`. If you omit the
`native.cgroupdriver` option,` cgroupfs` is used.
This example sets the `cgroupdriver` to `systemd`:
$ sudo docker daemon --exec-opt native.cgroupdriver=cgroupfs
$ sudo docker daemon --exec-opt native.cgroupdriver=systemd
Setting this option applies to all containers the daemon launches.
