Add cgroup support in the process view

Add a new 'Control Group' column to the process view tab.
The format for the column is:

<path name> (controller name), <path name> (controller name)...

Processes that share the same path name across controllers
are colesced. For example if a process is in the /foo cgroup
for both the memory and cpu controllers, it would display as:
/foo (memory,cpu), ...
