Title: Add ability to pause/unpause containers via cgroups freeze

This patch adds pause/unpause to the command line, api and drivers
for use on containers. This is implemented using the cgroups/freeze
utility in libcontainer.

This is possibly a WIP. We're running into an issue with the systemd implementation not supporting freeze. The fs version works well though.

This is a start to fix bug #5948
