Fix EventStreamSSE Memory Leak

Browse source 
The `Config.Services.Pubsub.Subscribe` is being initialized with the global Gin Context. This causes the publisher object to [hang at line 58](https://github.com/cncd/pubsub/blob/master/pub.go#L58) and the goroutine remains opened indefinetly, which can be a source of memory leak.

Setting it to the locally defined ctx object correctly causes the goroutine to close when the function exits due to the deferred close.

See https://discourse.drone.io/t/memory-leak-on-drone-server/1884 for further information.
