[ES] enhance es mapping for event

[andyxning]

This PR adds support for adding more info for analyze events in ElasticSearch. This PR adds EventType, EventKind, EventReason and EventMessage as tags and thus allows us to query based on them. Such as, what are the warning events in last two hours. When does the cluster emits FailedScheduling events.

This PR also adds the namespace tag info when the event is of Pod kind.

Can a kubernetes member verify that this patch is reasonable to test? If so, please reply with "@k8s-bot ok to test" on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands will still work. Regular contributors should join the org to skip this step.

If you have questions or suggestions related to this bot's behavior, please file an issue against the [kubernetes/test-infra](https://github.com/kubernetes/test-infra/issues/new?title=Prow%20issue:) repository.

I don't know why the test TestOneExportInTime in k8s.io/heapster/metrics/sinks will fail. I runs ok in my laptop. :(

it turns out that memory is out and something like go build testmain: /home/travis/.gimme/versions/go1.6.linux.amd64/pkg/tool/linux_amd64/link: signal: killed is reported. For more info please see Travis CI build envrionment and Travis CI FAQ about memory limit

That's an interesting approach, i solved that slight differently in #1313

Can anyone review it? @AlmogBaku?

[AlmogBaku]

I think it's now redundant after #1313 If you see any reason to implement it this way other than the method i used, can you elaborate?
