Describe the solution you'd like

Currently gopsutil have two versions, v2 and v3. But it is difficult to support both versions from our limited resource. I want to terminate v2 and move v3 version to root directory.

My plan is 6 months later, end of November of this year, this means 2021-11-30. After that day, we will not have v2 any more. Please migrate your code from v2 to v3 until that day.

Plan

• Oct.: check difference between v2 and v3. If there is something which v3 doesn't have, open a PR.
• Beginning of Nov.: Open a PR which move v3 to root, and check feasibility.
• End of Nov.: merge the PR.

Do you plan on removing v2 files or just freeze the sub-packages? I fear that that removing files would break a lot of things downstream.

Otherwise, I agree with the idea of freezing v2.

I am planning remove v2 files and move v3 to top. I understand it breaks a lot, but it's something we are going to have to do at some point.
