fix(server/server.go): /v2/stats endpoints emit application/json content type header
server: Flush headers when using wait=true and stream=true

Many http clients will missbehave unless they get an initial http-
response, even when long-polling. It also saves the user/client from
having to handle headers on the first action of the watch, but rather
handle the response immediately.

etcd: add a read/write timeout to server

The default is for connections to last forever[1]. This leads to fds
leaking. I set the timeout so high by default so that watches don't have
to keep retrying but perhaps we should set it slower.

Tested on a cluster with lots of clients and it seems to have relieved
the problem.

Running should be true when Start, and set to false when switching to

add the /version endpoint to the API docs

I had to find this by accident. It should be documented here.
