Modify priority tweaking to use CGroups.
This modifies the behavior of setpriority and getpriority
to use CGroups rather than niceness levels.
I've removed the unittest comparing priorities as its not
really valid any more as we are just writing numbers to files.
I've also refactored references to priority to reference cpu
shares etc.
