COOK-2356: Add status support to the rsyslog service

Option to preserve FQDN to remote syslog

RHEL6 and I'm pretty sure any rsyslog from the last few years
supports the notion of /etc/rsyslog.d/* files which can be
included from the main /etc/rsyslog.conf file, so the special
case in the template where non-Ubuntu would get a complete
/etc/rsyslog.conf has been removed. This means all hosts will
get the 50-default.conf and not just Ubuntu hosts. There was
nothing Ubuntu-specific about it at all, and so it is moved
into templates/default from templates/ubuntu.

Also removed the Ubuntu 8.04 special apt get stuff due to
age.

Move "arch" service name case from recipe into attributes, too

I see why this was done this way now (to allow support for
Ubuntu 8.04). Putting it back.

Default value is "/etc/default/rsyslog" but cased for redhat
to be "/etc/sysconfig/rsyslog"

Set user/group/priv_separation outside of platform case block
with sane defaults. Override in platform case block as needed.
Moved max_message_size up where it belongs, not dangling at
the bottom of the file.

This reverts commit 6e6b706b.

Per Mike Fiedler's comment on the COOK-1189 ticket, using "restart" is
the "Right Thing To Do".
