logging: introducing event router

Initial concept integrating kubernetes events to EFK stack using [eventrouter](https://github.com/heptio/eventrouter)
- **eventrouter** is deployed to logging project, has a service account and its own role to read events
- **eventrouter** watches kubernetes events, marshalls them to JSON and outputs to its STDOUT
- **fluentd** picks them up and inserts to elastic search logging project index

Kubernetes events could be easily stored into different index. Among other ways, it could be achieved either by a fluentd filter plugin or custom eventrouter sink.

Pending actions:
- [x] - get our downstream and upstream images for eventrouter, don't use heptio's
