Remove duplicate errors from an aggregate error input.

This PR, in general, removes duplicate errors from an aggregate error input, and returns unique errors with their occurrence count. Specifically,  this PR helps with some scheduler errors that fill the log enormously. For example, see the following `truncated` output from a 300-plus nodes cluster, as there was a same error from almost all nodes.

After this PR, the output looks like (on a 2-node cluster):

This directory is the staging area for packages that have been split to their own repository. The content here will be periodically published to respective top-level k8s.io repositories.

Most code in the staging/ directory is authoritative, i.e. the only copy of the code. You can directly modify such code. However the packages in staging/src/k8s.io/client-go/pkg are copied from pkg/. If you modify the original code in pkg/, you need to run hack/godep-restore.sh from the k8s root directory, followed by hack/update-staging-client-go.sh. We are working towards making all code in staging/ authoritative.

The vendor/k8s.io directory contains symlinks pointing to this staging area, so to use a package in the staging area, you can import it as k8s.io/<package-name>, as if the package were vendored. Packages will be vendored from k8s.io/<package-name> for real after the test matrix is converted to vendor k8s components.
