Goroutine leakage happening in create_service_instance,create_service_key,update_service_instance,delete_service_instance.

I see there is goroutine leakage. I was performing some operations like create service instance,create service key ,udpate service key , delete service key,delete service instance.
I observe following when I did some goroutine profiling -
**goroutine profile: total 8
2 @ 0x1032760 0x10420bb 0x1308069 0x105fc71

0x1308068 net/http.(*persistConn).readLoop+0x998 /usr/local/go/src/net/http/transport.go:2032

2 @ 0x1032760 0x10420bb 0x1309343 0x105fc71

0x1309342 net/http.(persistConn).writeLoop+0x122 /usr/local/go/src/net/http/transport.go:2210*

This readLoop and writeLoop goroutines are pilling up.

Should be resolved via #256
