Depends on intel/goresctrl#158

Haven't really looked at this, but as a nit you seem to lack a sign-off.

@klihub, this is the first time ever when I did it by purpose... It's the HACK commit that switches to use goresctrl from askervin's github branch with cstates support in it. I did not want to get that commit merged even accidently, so I thought that one way to get red flags would be leaving it unsigned. I'll fix it when the goresctrl PR is merged.

Now that intel/goresctrl#158 is merged and I've updated go.mod to pick the latest goresctrl from current main branch, this feature is ready for review. Rebased on top of nri-plugins to make sure tests are passing with the latest e2e changes, too. Looks good.

Converted to Draft.

Let's get @marquiz 's improvements in cstates filtering: intel/goresctrl#163 and tag goresctrl release, then update this PR to use new filtering before merging.
