[systest] Upgrade script returns non-zero value in 'rollback_automatically_simple_env' test

[Artem Panchenko]

In system test 'rollback_automatically_simple_env' we inject code with exception into the upgrade scripts, so it fails and performs automatic rollback:

https://github.com/stackforge/fuel-main/blob/master/fuelweb_test/tests/test_upgrade.py#L323

But 'run_script' method raises exception, because it expects that '0' will be returned by upgrade.sh script, so system test always fails (actually it also tries to get diagnostic snapshot, but docker containers aren't ready yet):

We should add an additional parameter 'exit_code' to the 'run_script' method and then in the 'rollback_automatically_simple_env' tests wait for exit code "255":
