RFS: arno-iptables-firewall/2.0.3-1 [ITA]

[Sven Geuer <debmaint@g-e-u-e-r.de>]

Hello team,

I intent to adopt the orphaned package arno-iptables-firewall (
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=915718). 

Marcos proposed to maintain this package from within the pkg-security
team and I would love to follow his suggestion.

Having read https://wiki.debian.org/Teams/pkg-security its still
unclear to me what the next steps shall be, starting with how to join
the team.

Please give some pointers or hints how to proceed.

Sven
