Fix memory limit support on Raspberry Pi#

If you run docker info and get warnings shown below, then you may need to enable memory limit support.

...
WARNING: No memory limit support
WARNING: No swap limit support
WARNING: No kernel memory TCP limit support
...

To enable memory limit support edit /boot/cmdline.txt and add this:

cgroup_enable=memory swapaccount=1 cgroup_memory=1 cgroup_enable=cpuset

Now reboot your Rasbperry Pi. You can confirm the warnings go away when running docker info. You should now recreate your containers that you want to have memory limits and you can confirm they are working by running docker stats --no-stream.
