[Plugin Request] Sentinel

Hi Aternos Team, can you please add the following plugin?

Plugin name:Sentinel
Plugin link: https://www.spigotmc.org/resources/sentinel.22017/
Description: Adds full high powered combat NPCs to your Spigot server! Requires Citizens2.
Also, this is the updated version of Sentry which is already in Aternos library. So it would be helpful to upgrade.

Thank you!
