1. config-linux: add CFS bandwidth burst …

   Burstable CFS controller is introduced in Linux 5.14. This helps with
   parallel workloads that might be bursty. They can get throttled even
   when their average utilization is under quota. And they may be latency
   sensitive at the same time so that throttling them is undesired.
   
   This feature borrows time now against the future underrun, at the cost
   of increased interference against the other system users, by introducing
   `cfs_burst_us` into CFS bandwidth control to enact the cap on unused
   bandwidth accumulation, which will then used additionally for burst.
   
   The patch adds the support/control for CFS bandwidth burst.
   
   Fixes opencontainers#1119
