cb9a3e04b1 client: fix goroutine leak in unreleased context 
If headerTimeout is not zero then two context are created but only one is released.
cancelCtx in this case is never released which leads to goroutine leak inside it.

f4c29a5f55 client: support to set timeout for each request 
Add HeaderTimeout field in Config, so users could set timeout for each request.
Before this, one hanged request may block the call for long time. After
this, if the network is good, the user could set short timeout and expect
that API call can attempt next available endpoint quickly.

78af793338 client: return context canceled error correctly 
If the body is closed to stop watching, it will ignore the error from
reading body and return context error.

Before this PR, the cancel when watching always returns error `read tcp
127.0.0.1:57824: use of closed network connection`. After this PR, it
will return expected context canceled error.

cfeaf3d172 client: return correct error for 50x response 
etcd always returns 500/503 response when it may have no leader.
So we should log the other 50x response in a normal way.

This helps to log correctly when discovery meets 504 error. Before this
PR, it logs like this:

```
18:31:58 etcd2 | 2015/08/4 18:31:58 discovery: error #0: client: etcd
member https://discovery.etcd.io has no leader
18:31:58 etcd2 | 2015/08/4 18:31:58 discovery: waiting for other nodes:
error connecting to https://discovery.etcd.io, retrying in 4s
```

After this PR:

```
22:20:25 etcd2 | 2015/08/4 22:20:25 discovery: error #0: client: etcd
member https://discovery.etcd.io returns server error [Gateway Timeout]
22:20:25 etcd2 | 2015/08/4 22:20:25 discovery: waiting for other nodes:
error connecting to https://discovery.etcd.io, retrying in 4s

6312e22b1d client: handle empty watch responses elegantly 
Even though current etcd does not time out
watches, the client could be running against
an old etcd version or the server may close
polling connection for other reasons.
This patch ignores successful (as in 200)
responses with emtpy bodies instead
of producing JSON errors.

1. When reset endpoints, client will choose a random endpoint to pin.
2. If the pinned endpoint is healthy, client will keep using it.
3. If the pinned endpoint becomes unhealthy, client will attempt other
endpoints and update its pin.
