Previously the logging to TravisCI has been disabled because the `print-logs.sh` file printed the Sauce-Connect logfile output that is `verbose` by default. See [for example](https://travis-ci.org/angular/angular/jobs/250578973).
Since the default stdout/stderr of sauce-connect is pretty much concise and can alert us if we run into any issues (e.g. rate limit, outdated tunnel version), we should stop piping these to `/dev/null`.
PR Close#27657
This is to prevent Travis from prematurely shut down the VM while we are still waiting for the sauce connect client
to tear down the tunnel.
Closes#4335
