sched: Throttle qos cfs_rq when current cpu is running online task


hulk inclusion
category: feature
bugzilla: 51828
CVE: NA

--------------------------------

In a co-location scenario, we usually deploy online and offline
task groups in the same server.

The online tasks are more important than offline tasks. And to
avoid offline tasks affects online tasks, we will throttle the
offline tasks group when some online task groups running in the
same cpu and unthrottle offline tasks when the cpu is about to
enter idle state.
