Upgrade Fail2Ban in distro from 0.8.14 to 0.11.1
The existing package in the SNG7 distro uses fail2ban
0.8.14 which is quite old. This commit includes the
SRPM and RPM files for 0.11.1. Also included are some
upstream changes from Fail2Ban's asterisk jail conf
to better match rules in modern Asterisk versions.
