Clojurians Log v2

It's been a little longer than I expected, but I'm using some of my 20% time at Cognitect to work on issues and PRs in lacinia. It's good to be back.

Just pushed lacinia 1.2-alpha-2 to clojars

I'm looking at https://github.com/walmartlabs/lacinia-pedestal/issues/112 and I'm throwing the floor open about what the lacinia-pedestal behavior should be when an operation times out. My initial take is that the lacinia-pedestal handler should throw an exception so that an application-specific interceptor can handle the exception - that interceptor could log the exception and decide what kind of response to send to the client.
