Workflow Test

Have made two test on the model uploader workflow, one for sparse model and another for dense model. The steps failed just because the repo maintainer doesn't match. And for sparse model, I have upload 3 models to s3 by this PR, and deployed on a local opensearch cluster with a success inference.
