util, finagle, finatra, scrooge: Bump sbt-jmh plugin version to 0.4.0

Problem:

The latest version of the sbt-jmh plugin for running JMH microbenchmarking is
0.4.0. This version supports sbt 1.3.0+ and JMH 1.25. One feature of JMH 1.25
that we can take advantage of is the async profiler for profiling CPU cycles,
cache misses, and stack traces. We are currently on 0.3.4.

Solution:

Bump the sbt-jmh plugin version to 0.4.0
