After a brief skim of the configuration docs [1], I'm in favor of switching
in a follow-up RB to https://reviews.apache.org/r/41777/
In short - logback supports pointing to a non-root config file via a
system-property out of the box, this makes aurora a non-nuisance for
operators, they can easily modify init scripts to point to a custom config.
