Vendor GetTotalMemoryWithoutLogging from github.com/cockroachdb/cockroach

Is there any chance we can get https://github.com/cockroachdb/cockroach/blob/7fe21a3b907aa148fcccc8ba62b9ac4db1ada50f/pkg/server/status/recorder.go#L644-L683 (and all child functions) vendored into this repo? Right now we have to copy over the code because importing github.com/cockroachdb/cockroach into our project isn't feasible. It would be great to have the same code that detects the memory usage available in this library since the testserver uses that value.
