Description

When cassandra is started via systemd, it would be nice to support the SD_NOTIFY protocol so systemd know, when cassandra is ready (that can be use for dependencies or when you need to wait until cassandra startup is done).
A very simple implementation could be done using the

systemd-notify --ready

command line tool (and ignore it if the tool is not there)
