View Source GlificWeb.InjectOban (Glific v5.1.6)

Simple macro to conditionally load Oban.Web only if already loaded. This allows us to include it only in the production release and hence make it a lot easier on potential open source contributors. We thus avoid the problem of sharing the oban key and/or them hacking the code to get it working

Thanx to @manu from DataOGram and @benwilson from Absinthe/GraphQL for help with this feature.
