ExpectProcess and ExpectFunc now take the exit code of the process into
account, not just the matching of the tty output.
This also refactors the many tests that were previously succeeding on
matching an output from a failing cmd execution.

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.

The fix is needed to mitigate consequences of
https://github.com/golang/go/issues/29458 "golang breaking change" that
causes following test failures on etcd end:
--- FAIL: TestCtlV2Set (0.00s)
ctl_v2_test.go:552: could not start etcd process cluster (fork/exec ../../bin/etcd: Setctty set but Ctty not valid in child)
--- FAIL: TestCtlV2SetQuorum (0.00s)

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.
