I think we should move out the core CPU groups support into an internal/cpugroup package, and just call into that from uvm.SetCPUGroup and uvm.UnsetCPUGroup.

There are some standalone pieces that I moved out, but the code that needs to be run in Set/Unset/Release require the uvm package, so I did not move those. Let me know if it looks okay.

Can omit the part of the comment that mentions this is for the UVMs host as this is in a more general package now.

This PR adds a new annotation
io.microsoft.virtualmachine.cpugroup.idfor pod configuration that allows for specifying the ID of a cpugroup the corresponding UVM should be added to. This PR also adds e2e tests and a unit test, which is disabled since cpugroups is only enabled on systems with classic/core scheduling type.Signed-off-by: Kathryn Baldauf kabaldau@microsoft.com
