chef is calling update-rc.d with the deprecated "-n" flag

[Coops]

After upgrading to 18.06 LTS, chef (specifically chef-solo) breaks when trying to enable services.

The "-n" flag was removed from "update-rc.d" upstream here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=856415

However chef (12.14.60-3ubuntu1) still uses it, which breaks configs. Example chef error:

```
    * service[xinetd] action enable
    * /usr/sbin/update-rc.d -n -f xinetd failed - #<Process::Status: pid 23972 exit 1>
```

Status changed to 'Confirmed' because the bug affects multiple users.

This issue was fixed in this commit in Chef. It's a 6 character diff. https://github.com/chef/chef/commit/5320cbf9b41789a46a5c5c0a2d818966c9716405?diff=unified#diff-8561ad40ccb208ff3c3f12bf88746df2

I'm not sure how to go about submitting a patch to a package in Ubuntu, but I'll look into it.

Consider using upstream Chef >= 14.1.1 instead of the Chef package from the Ubuntu repository. Upstream Chef has Ubuntu 18.04 support.

Easier said than done, seeing as AWS ubuntu 18.04 currently only has support up to Chef 12.18.31. IOW, it's impossible to do an OpsWorks run command that tries to do a update-rc.d -n ... (so much for no-ops)

@ellayararwhy you can workaround this by setting the service provider to systemd, like:

service 'example_service' do
  provider Chef::Provider::Service::Systemd
  action [:enable, :start]
end
