This should aid in debugging test flakes, especially in tests where the process is restarted very often and thus changes its pid.
Now it's a lot easier to grep for different members, also when different tests fail at the same time.
The test TestDowngradeUpgradeClusterOf3 as mentioned in #13167 is a good example for that.

Not all systems include binaries in the same location. On my (NixOS, so
albeit a little weird) system these binaries exist in very different
locations.
This test switches to looking up the paths from the users PATH or skips
the test if they do not exist to improve the `make test` experience on
such systems.
The fix is needed to mitigate consequences of

Update to Go 1.12.5 testing. Remove deprecated unused and gosimple
pacakges, and mask staticcheck 1006. Also, fix unconvert errors related
to unnecessary type conversions and following staticcheck errors:
- remove redundant return statements
- use for range instead of for select
- use time.Since instead of time.Now().Sub
- omit comparison to bool constant
- replace T.Fatal and T.Fatalf in tests with T.Error and T.Fatalf respectively because the goroutine calls T.Fatal must be called in the same goroutine as the test
- fix error strings that should not be capitalized
- use sort.Strings(...) instead of sort.Sort(sort.StringSlice(...))
- use he status code of Canceled instead of grpc.ErrClientConnClosing which is deprecated
- use use status.Errorf instead of grpc.Errorf which is deprecated

bufio.NewReader.ReadString blocks even
when the process received syscall.SIGKILL.
Remove ptyMu mutex and make ReadString return
when *os.File is closed.

add and expose StopSignal to ExpectProcess allows user
to define what signal to send on ExpectProcess.close()
coverage testing code sets StopSignal to SIGTERM allowing
the test binary to shutdown gracefully so that it can generate
a coverage report.
