Improve documentation of Suricata-Update according to the different reload methods of Suricata
The documentation of Suricata-Update only names the "kill" command for a Suricata reload.
--reload-command='sudo kill -USR2 $(cat /var/run/suricata.pid)'
But according to the official Suricata documentation, there are much more commands for reloading.
For example using:
suricatasc -c reload-rules
In our deployment, the documentation of Suricata-Update led to a little confusion on how to correctly reload Suricata after an Suricata-Update run. We're doing this in a cronjob, but that doesn't really matter here.
In this ticket I will try to improve the documentation of Suricata-Update to clarify this.
