Node lookup fails when --watch-namspace is present on ingress controller

[joshrosso]

When writing an ingress controller that looks up Nodes via the StoreLister the API query sent is invalid when --watch-namespace is present. Consider the following example where --watch-namespace is set to test-nm.

The ingress controller's logs will print the following:

pkg/ingress/controller/controller.go:1037: Failed to list *api.Node: the server could not find the requested resource

The API server, with --audit-log-path set, will print the following:

/api/v1/namespaces/test-nm/nodes?resourceVersion=0: (329.906µs) 404

Note the inclusion of /namespaces/test-nm resulting in a 404.

After removing --watch-namespace and redeploying, the query is valid and nodes are returned. An example query sent to the API server is now:

GET /api/v1/nodes?resourceVersion=0: (782.297µs) 200
