Split out of #50, which is getting mirth.properties.d support for the main config. Logging was deliberately left out of that PR.
log4j2's log4j2.configurationFile accepts a comma-separated list of files and merges them into a CompositeConfiguration, which might make this nearly free. Two things need checking before trusting it: the merge machinery is documented around XML/JSON/YAML and its behavior with properties-format configs (what we ship) needs empirical verification on our log4j version, and the launcher hardcodes ./conf/log4j2.properties in Log4jBootstrap/Log4jMigrations.
