Fix incorrect  pod spec
Don't assume every AWS VPC has tags

The default VPC has no tags (by default), so we should use get()

Otherwise kube-down fails because the variable is not defined

No need to add two "containers" section for one pod

Fix issue #2664
Fixes #2681: update to cadvisor 0.6.2
Make credentialprovider less verbose about benign errors.

In particular, a few of the utilities used within the credentialprovider had the pattern:
   glog.Errorf("while blah %s: %v", s, err)
   return nil, err

This change propagates those error message and puts the burden of logging on the caller.

In particular, this allows us to squelch all output during kubelet startup when we are detecting whether certain credentialprovider plugins should even be enabled.
