python: tools: Add tool for displaying a list of realtime data

Add a tool for displaying the realtime allocations for a cgroup
hierarchy.

$ ./src/tools/cgrealtimelist.py -C application.sliceRUNTIME  PERIOD PERCENT CGROUP
   1000    8000  12.50% /child2.service
   5000  100000   5.00% /child1.service
  20000 1000000   2.00% /child3.service

10,000 / 50,000 microseconds (20.00%) of the CPU cycles have been allocated to realtime in the root cgroup.

9,750 of the 10,000 realtime cycles (97.50%) for /application.slice have been assigned to children cgroups

5,000 (cpu.rt_runtime_us) / 1,000,000 (cpu.rt_period_us) microseconds can still be assigned to a child of /application.slice

Note that the remaining cpu.rt_runtime_us is estimated and could be off by 1 or 2 in either direction.

$ ./src/tools/cgrealtimelist.py

   1000  100000   1.00% /init.scope

950,000 / 1,000,000 microseconds (95.00%) of the CPU cycles have been allocated to realtime in the root cgroup.

361,111 of the 950,000 realtime cycles (38.01%) for the root cgroup have been assigned to children cgroups

588,888 (cpu.rt_runtime_us) / 1,000,000 (cpu.rt_period_us) microseconds can still be assigned to a child of the root cgroup

Note that the remaining cpu.rt_runtime_us is estimated and could be off by 1 or 2 in either direction.
