SROS2 services and actions status

I’ll try and break out a few more tickets on ros2/sros2 repo with various areas to get involved. Creating a sros2 equivalent to AppArmor’s aa-logprof is high on my personal list. However, I’m not sure who or to what extent DDS vendors have implemented support for the default Builtin Logging Plugin defined in OMG’s DDS Security specification (section 8.6.2 and 9.6). This would be quite helpful in logging and scraping security events for policy modeling and training.
