etcd3/watcher: Event.Object should have the same rev as etcd delete
### What's the problem?
When a delete is watched, the revision should be larger than any previous to guarantee ordering. However, currently etcd3 decodes the previous rev into returned object:
995f022808/pkg/storage/etcd3/watcher.go (L322)
This will break, for example, cacher's assumption here if it re-watch.
995f022808/pkg/storage/cacher.go (L579-L581)
The etcd2 impl. also takes the current ModifiedIndex to ensure it's a larger number:
995f022808/pkg/storage/etcd/etcd_watcher.go (L437-L442)
### What's this PR?
It fixes above problem by using etcd's delete revision.

kubenet try to retrieve ip inside pod net namespace
Kubenet currently stores the ips of pods inside a map. Kubelet gets pod ip from kubenet during syncpod. If Kubelet restarts, all pods on the node lost their ips in podStatus. This PR adds logic to retrieve pod IP from pod netns.

This prevents programmer error from resulting in objects serialized to
the wire that are incorrectly designed. The normal path guards against
this, but the runtime.Unknown NestedMarshalTo fast path (which avoids an
allocation) doesn't have the same defensive guard.

Use constructor for ecrProvider
Rename package to "credentials" like golint requests
Don't wrap the lazy provider with a caching provider
Add immedita compile-time interface conformance checks for the interfaces
Added comments
This is step two. We now create long-lived, lazy ECR providers in all regions.
When first used, they will create the actual ECR providers doing the work
behind the scenes, namely talking to ECR in the region where the image lives,
rather than the one our instance is running in.
Also:
- moved the list of AWS regions out of the AWS cloudprovider and into the
credentialprovider, then exported it from there.
- improved logging
