0558b546ff fix(registry): fetch peers from store instead of cache 
The current cache implmentation may contain removed machines, so we
fetch peers from store for correctness.

4e14604e5c refactor(server): add Client struct 
This is used to send request to web API.
It will do this behavior a lot in standby mode, so I abstract this
struct first.

e55512f60b fix(peer_server): graceful stop for peer server run 
Peer server will be started and stopped repeatedly in the design.
This step ensures its stop doesn't affect the next start.
The patch includes goroutine stop and timer trigger remove.

d73390a674 fix(server): avoid race conditions in Run/Stop 
- don't close ready channel until PeerServer is listening.
  avoids possible panic in Stop() if PeerServer is nil.

- avoid data race in Run() (err variable was shared between 2 goroutines)

- avoid data race in PeerServer Start/Stop (PeerServer.closeChan)

4fd9e627c0 fix(peer join) fix wrong join command redirection 
1. We use PUT request to do a V2 join. So we should redirect a PUT request rather than a POST.
2. /admin only accept V2Join request. Send out V2Join instead of V1Join.
