I like loopabull, having been pretty much the only one playing with it since
Adam, I think it's a nice and fine tool and we should try leveraging it.
There is one angle where it isn't straight forward to use, it's secrets.
Currently the API tokens the scripts are using are passed as CLI argument when
calling the script.
If we end up needing something like kerberos keytab for example, we may have to
think how to do this and evaluate if loopabull is still a good fit.
