Bump gw/faas-netes + fix label update

Now that we have a label selector which is distinct from our own
labels we have to update the deployment labels in the update code.

Bumps GW to 0.8.2 (basic auth support) and faas-netesd to latest
for label enhancements. Tested on GKE 1.9.6.

Move label query to deployment.labels

When querying labels we were returning the selector labels instead
of the deployment labels. This change corrects the regression
which was introduced in 0.5.3.

Add Selector for deployment

A bug was found where updating through OpenFaaS-Cloud without a
faas_function label was causing an error with the buildshiprun
function. The label selector is required so we have an implicit
match and do not allow K8s to assume we want to match on all labels
because when it does - that means we can't change those labels in
an update.

Tested on kubeadm 1.9.6.
