with detached mode, we don't need to wait for the
tests to complete. Now, we can get inside tmate before
the tests start and we can monitor the tests.
By default, this mode will wait at the end of the job for
a user to connect and then to terminate the tmate session.
If no user has connected within 10 minutes after the post-job step started,
it will terminate the tmate session and quit gracefully.
