Would you accept a PR that adds a GoTestEngine?

While I know it's not precisely an extendible test engine like TapTestEngine, it does only work in the MultiTestEngine context.. I'm happy to send a PR if you're cool with it.

final class GoTestEngine extends ArcanistUnitTestEngine {
public function run() {
$command = $this->getConfigurationManager()->getConfigFromAnySource('unit.engine.go.command');
$future = new ExecFuture($command);

do {
  list($stdout, $stderr) = $future->read();
  echo $stdout;
  echo $stderr;
  sleep(0.5);
} while (!$future->isReady());

list($error, $stdout, $stderr) = $future->resolve();

$parser = new ArcanistGoTestResultParser();
return $parser->parseTestResults("", $stdout);

}
}

Sure thing! Sorry for the delay, I am not being able to review your PRs, I will take a look at this soon.
