This removes some qualifiers that aren't necessary (e.g. public/abstract on interfaces, private on enum constructors, final on private methods, static on nested interfaces/enums), uses Java 8 lambdas and features where that's an improvement

We're already storing this as a metric, but on a registry of our
scale these operations tend to only happen on a daily-ish basis,
for which seeing results in logs is easier to deal with than metrics
(and also still very light-weight).

We want to know how long it's actually taking to process asynchronous
contact/host deletions and DNS refreshes on host renames. This adds
instrumentation. Five metrics are recorded as follows:
* An incrementable metric for each async task processed (split out by
type of task and result).
* Two event metrics for processing time between when a task is enqueued
and when it is processed -- tracked separately for contact/host
deletion and DNS refresh on host rename.
* Two event metrics for batch size every time the two mapreduces are
run (this is usually 0). Tracked separately for contact/host deletion
and DNS refresh on host rename.
