Add shutdown callback to ServerController

kkhan: Is there something I can wait for to know that a StandaloneServer instance has a) been completely started b) been completely stopped?

[15:07] dmlloyd: not sure if we ever did that, but if so you could just have a remove listener on that
[15:08] kkhan: How would I access that without access to the server controller? By registering a listener on startup?

[15:19] dmlloyd: (yes, it does)
[15:23] kkhan: That ^ sounds like a good idea
