Fix pointer receiver handling in queryparams marshaler
**What this PR does / why we need it**:
`Time.MarshalQueryParameter()` and `Time.MarshalJSON()` try to handle nil pointer object (they call `t.IsZero()` which checks if t == nil) but fail because receiver is not a pointer so the dereference needed to pass it as receiver to these methods fails with npe.
In practice this happens with `Unstructured.SetDeletionTimestamp(Unstructured.GetDeletionTimestamp())`.
Here is the stacktrace of the failing test if receiver is not a pointer.
```go
panic: runtime error: invalid memory address or nil pointer dereference [recovered]

To be consistent with http package, check also no_proxy
**What this PR does / why we need it**:
Default http.ProxyFromEnvironment uses uppper case proxy
environment variables first, and if they are not defined,
tries lower case. For NewProxierWithNoProxyCIDR we should
provide similar user experience.
Example: cluster will not be able to access service or pod CIDRs in case user uses lower case version of proxy variables.

Fixed intermitant e2e aggregator test on GKE.
**What this PR does / why we need it**: Issue was caused by another test cleaning up its namespace.
This caused the namespace controller to try to clean up that namespace.
This involves deleting all flunders under that namespace.
However the sample-apiserver was not honoring the namespace filter.
So the flunders for the test would randomly disappear.

ProducesObject should only update the returned API object resource documentation
This should be a no-op for Kubernetes (the only rest.Storage that specifies ProducesObject() is pod logs, on GET), but will allow issues such as openshift/origin#8345 to be resolved (where generated API documentation is currently incorrect due to the asymmetry between the object kind sent and received by the API)

Preserve leading and trailing slashes on proxy subpaths
subresource parsing was not populating path parameters correctly (leading and trailing slashes were being stripped)
this caused bad locations to be sent to the proxy, causing https://github.com/kubernetes/kubernetes/issues/52022. the first attempt to fix that (#52065) unconditionally prefixed '/', which broke the redirect case (#52813#52729)

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.
