Adding to tomcat's server.xml

[tscibilia]

I'm looking to modify the tomcat server.xml file to properly display the x-forwarded-for IP address of the client connection made to guacamole as described in the docs here https://guacamole.apache.org/doc/gug/reverse-proxy.html#setting-up-the-remote-ip-valve. Is there a convenient was to possible mount that file in the docker-compose file?
