Make storage_io_exception exception error message less cryptic by actually including the human-readable error message from std::system_error... Before: nodetool: Scylla API server HTTP POST to URL '/storage_service/snapshots' failed: Storage io error errno: 2 After: nodetool: Scylla API server HTTP POST to URL '/storage_service/snapshots' failed: Storage I/O error: 2: No such file or directory We can improve this further by including the name of the file that the I/O error happened on.
