Michael Hoyle c29271e168 Revert "Revert "metrics: Add metrics crate."" ... This reverts commit 55a5c8d8f9. In order to accommodate the removal of the UnixSeqPacket+CloseNotifier change, I updated the controller.rs to reference platform-specific internal implementations. On Windows, CloseNotifier is used to detect closed Tubes. On Linux, we rely on PollContext returning because the socket fd is hung up. Some minor adjustmets to the code were made just to allow as litte duplication as possible. In the end, very little logic has changed from the original CL, it's just moved around. TL;DR: This fixes the downstream regression by removing its dependency on the breaking changes to base.
