In autoscaling tests, improve setting pdbs for kube-system pods
This fixes selector for l7-default-backend pod and removes Heapster's PDB (it's harmless but pointless as CA won't be able to evict it due to other constraints).

Don't specify clusterIP in dns e2e test
**What this PR does / why we need it**:
Different upgrade tests may configure different service clusterIP ranges. If we specify the clusterIP in dns e2e test, it will succeed in one upgrade test but fail in another. This PR doesn't specify clusterIP. It just uses the allocated clusterIP.

update-staging-godeps: only mangle staging repos in staging Godeps.json
- this re-adds non-staging k8s.io/* repos to the staging Godeps.jsons
- x-outs instead of removing of staging dependencies in order to get a
precise trigger for a complete godep restore+save run in the publisher
bot.
The first breaks k8s.io/kube-aggregator's staging export.
The second potentially leads to inconsistent godeps in our exported staging repos.

conversion-gen: make staging dirs independent of living in vendor/
The `+k8s:conversion-gen` tags included the package directory inside of kube's vendor dir. This
makes them invalid when we publish staging repos.
Without this PR our sample-apiserver example code-generation is broken once published.
