Add ability to add config files when using druid on Kubernetes (#13795) 

You can now add additional configuration files to be copied to the final conf directory on startup when running in a containerized environment. Useful for running on Kubernetes and needing to add more files with a config map. To specify the path where the configMap is mounted, utilize the DRUID_ADDITIONAL_CONF_DIR environment variable.
