Rename main launch method and expose Metric data

Summary:
1. Rename launch method from main to launch_workflow so users can write custom wrappers to configure for example metrics handler
2. Expose MetricData class so users can write custom metrics handler
3. Rename with_etcd parameter to with_embed_backend to indicate that there is an embedded backend for torchelastic, but eventually it can change from etcd to something else.
