* Changes the wait timeout for Saucelabs and Browserstack from 2 minutes to 1 minute. This is possible now because if the timeout fails we still re-try to create a connection a second time.
* The logfile output should be printed if the tunnel connection can't be established. The logging is also useful to see the update message from Saucelabs for example.
* Suppresses normal log messages from Saucelabs Conect. Error messages will still show up (In a follow-up PR the normal stdout will be printed together with the stdout on CI failures)
* No longer suppresses the whole Browserstack Tunnel execution. Stderr output will be printed if present. (In a follow-up stdout will be printed as well on CI failures)
* Switches to best-practice variable referencing in Bash
* chore: remove inactive browserstack wrapper package
No longer uses the "inactive" browserstack wrapper package from npm,
which was just responsible for creating the readyfile.
We can create the readyfile ourself and get rid of the npm package.
* Fix incorrect comments
* Don't wait for tunnel if timer exceeded
* Fix race conditions
* Add empty line before logging that the tunnel is ready.
