Propagate labels from profile custom resource to controller-generated namespace

[droctothorpe]

/kind feature

Why you need this feature:
We use the profile operator directly instead of pathing through the UI. We want end user namespaces to have specific labels (that identify various things about the user). This code lets administrators set global namespace labels, but there's no mechanism to pass custom-resource-specific, non-global labels.

Describe the solution you'd like:
The simplest way to implement this is to just propagate labels from the profile custom resource to the corresponding namespace. It's a one line change to the controller logic.

Anything else you would like to add:
I'll submit a PR momentarily.
