[proposal] support pod level resctrl enhancement

[kangclzjc]

What is your proposal:
Koordinator support LLC and MBA configuration and adjustment by config map based on class level. As Koordinator already support NRI in 0.3.0 release, we want to add pod-level LLC/MBA configuration/adjustment. This is part of #1798

Why is this needed:
If there exists noisy neighbor, this feature can limit noisy neighbor's LLC and MBA.

Is there a suggested solution, if so, please add it:
