This reduces the total number of git repos we need to manage as we
migrated away from puppet. Keeping this pruned is a good way of tracking
progress and should make the jobs more reliable until we can delete
them.
In this change remove modules that have moved to base server roles
like ntp and haveged. Also removed are ircbot management,
selinux (no more centos here), haproxy (this moved into ansible with
gitea), and lodgit modules.
