Upgrade to golang 1.11 to fix server context deadline exceeded #210
Description
If the Atlantis server is running and you load its UI from Chrome and then Ctrl-C the server, you see this message:
^C2018/08/04 12:27:12 server.go:391: [WARN] server: Received interrupt. Safely shutting down
[ERROR] while shutting down: context deadline exceeded
This is because Chrome will open up multiple connections and send no bytes. The current implementation of golang server won't close these connections and will assume they're still open. Eventually the context will time out and we'll get that error.
The issue (golang/go#22682) is fixed in golang 1.11 which is currently in beta but should be released in August of this year.
