bash error handling and reporting is atrocious. Without -e it will just ignore errors. With -e it will stop on errors, but not report where the error happened (apart from exiting itself with an error code). Improve that with the `trap ERR` command. Note that this won't be invoked on intentional error exit with `exit 1`. We apply this on every bash script that contains -e or that it appears trivial to set it in. Non-trivial scripts without -e are left unmodified, since they might intentionally invoke failing scripts. Closes scylladb/scylladb#22747
