Should we change ```_local``` to ```local``` in ```GET _cluster/shard_routing/weights?_local``` to keep it consistent with other _cluster/* apis like _cluster/state.

> Default looks like - {"msg":"Weights are not set"}. Shouldn't we just return empty object {} Will make the response empty object

Seeing unrelated test failures

> Can we add integ tests for the API Added Integ tests
