* Add more details: name & namespace, service name
* Refresh the view on replicas change
* Overall design refresh of the left menu

This gives way more information than just current/desired numbers as it
was previously. Fixes #247.

Now raw data is gathered on the backend and rendered on the frontend.

Added check to prevent display of replica set list page when there are no replica sets.

The tests cover all methods except the one that interacts with the
client. Test for it will be added later.

This change handles replica set description end-to-end: saving in on the
deploy form and then displaying. It also handles replica set endpoints.
I also attempted to write tests for the go code, but this change grew
too much. I'll do this later.

The implementation consists of backend code and sample frontend view
that dumps the data into an ugly looking table. Subsequent changes will
implement frontend so that things look pretty.

The cards now display mostly fake data, but they look more complete. The
backend will be implemented soon.

Per discussion in: https://github.com/kubernetes/dashboard/issues/65

This change does only renaming, no functional modifications.

1. This is a model for mocks:
https://github.com/kubernetes/dashboard/blob/master/designs/11-11-2015/16_card%20variations.png
2. Did little renaming (used the word "microservice") until we agree what the list exactly shows.
3. The implementation is very basic and will evolve over time.
