Hi all, can I connect to a MySQL database asynchronously in an interceptor?

Something I noticed when upgrading from 0.5.3 to 0.5.4 was that Pedestal is now intolerant of nils in the interceptor list; previously it would skip over the nils, but now it fails. I had to change some setup code, that had some conditional parts in it, to filter out the nils before passing them to io.pedestal.http/create-server.
