CPU pinning workloads

As a user, I’d like to express a tolerance for CPU and memory for whole-core increments, like what we did for throttling. I'd like to set equal CPU request and limit (for OCR).


PM update to requirement:

We will implement support for rightsizing CPU Pinned workloads in 2 parts:

  1. introduce a setting that a user will specify locking limits and requests to resize together - a must to maintain the requirements for pinning workloads to a CPU

  2. introduce a setting where the user can express a toleration for CPU usage. Here the goal will be to allow pinned workload to have a targeted utilization of 50% or 25% which will influence the resizing to recognize scenarios where 1 out 2 or 1 out of 4 cores are in use.

Today the user can choose to set whole core increments for rightsizing but needs these other 2 features to ensure best actions for workload that is pinned to a CPU.
