* Add OpenRC conf.d file for Netdata. * Tidy-up handling of retry schedule. It should be computed in stop_pre so it gets evaluated after the conf file, and it also needs to handle variables not being defined properly (which it currently does not). * Add a service description and command descriptions. * Only install `/etc/conf.d/netdata` if it does not already exist. This prevents overwriting user configuration.
