Can't set deployment namespace with simple ".withNamespace" mixin

[fabioy]

When using deployment object, somehow the mixins get confused, so the top level ".withNamespace" sets it for the pod template, and not the deployment:

Repro:

local appDeployment = deployment
.new(
"heptio-server",
4,
serverContainer,
params.labels)
.withNamespace("heptio-svc");

Expected: deployment within given namespace.

Result: Sets the namespace in the pod spec.

Workaround:

The workaround is a bit hard to discover, but this works:

local appDeployment = deployment
.new(
"heptio-server",
params.replicas,
serverContainer,
myparams.labels)+
deployment.mixin.metadata.withNamespace("heptio-svc");

AFAICT this is because scoped withX methods are used which change the mixins in the associated object. Seems to be a somewhat pervasive problem, though most easily seen in Deployment because of the nested nature of the objects. Essentially, the Deployment you get back is broken.
