attach_compute should set exit code after exception

[algattik]

I got a transient service error while retrieving compute. An error was logged but the pipeline continued. The script fails to set an exit code when catching the exception:

MLOpsPython/ml_service/util/attach_compute.py

Line 42 in d4a7633

exit()
