centos install docs

I used the following steps to configure this on centos:

   29  cd /var/aegir/hostmaster-6.x-1.5/sites/aegirnt2.uqam.ca/modules/hosting_queue_runner/
   30  cp init.d.example /etc/init.d/aegir
   31  chmod a+x /etc/init.d/aegir
   74  chkconfig aegir on
   75  chkconfig --list aegir

The init.d had to be patched as it is debian-specific, here is the result:

#!/bin/sh
### BEGIN INIT INFO
# Provides:          hosting-queue-runner
# Required-Start:    $network $local_fs
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Queue runner daemon for Aegir
# Description:       This module allows the Hosting tasks queue for the
#                    Aegir project to be 'daemonized' so that tasks
#                    are run as soon as possible instead of waiting
#                    for a cron run. This makes Aegir appear much more
#                    responsive.
