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:

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.
