Review comment:
So, this is used as an optional dependency of log4j2, that enables the
high-performance asynchronous loggers. It is required on the class path if
`-Dlog4j2.contextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector`
system property is set. I set it by default in our example `accumulo-env.sh`,
because there's no good reason to not have it, since it's ALv2 licensed has no
deps.
