68e3d394ab* Implement filtering for stepfunctions:ListExecutions * Add pagination to Step Functions endpoints Implements a generalized approach to pagination via a decorator method for the Step Functions endpoints. Modeled on the real AWS backend behavior, `nextToken` is a dictionary of pagination information encoded in an opaque string. With just a bit of metadata hard-coded (`utils.PAGINATION_MODEL`), backend `list` methods need only be decorated with `@paginate` and ensure that their returned entities are sorted to get full pagination support without any duplicated code polluting the model.
