Kedro

Hey Team! :hand:

I have multiple kedro pipelines in my project. Each kedro pipeline is also namespaced by its own name.
For example, a pipeline named `my_pipeline` is namespaced as `my_pipeline` to allow multiple benefits (separation of parameters, filtering of nodes using namespace + tags etc).

But the following command fails:

```kedro run --namespace=my_pipeline```
with the error:
```ValueError: Pipeline does not contain nodes with namespace 'my_pipeline'```
But it works when I include the pipeline name

```kedro run --pipeline=my_pipeline --namespace=my_pipeline```
But it fails if I pass it any other namespace (expected)

```kedro run --pipeline=my_pipeline --namespace=xyz```
Can you help me where I am going wrong here? Seems like something very basic I am missing!

Thanks! :slightly_smiling_face:

*Update:* I think I know what is happening.

`kedro run --namespace=my_pipeline` will search for nodes with namespace in the default pipeline and not across all pipelines.
