Support el8

[anders-larsson]

First commit is to ensure spec tests continue to work for ruby 2.1.9.

Adds support for EL8-based distributions.

Oops. I had totally missed #68. Well now you have two pull requests for EL8 @ghoneycutt.

Thanks for your work.

Is nscd even used on EL8? I thought it was deprecated in EL7 in favor of sssd.

[anders-larsson]

Hm. Yes it appears that they think sssd and nscd might duplicate caching functionality. I do think it serves a purpose though when used in combination with other applications.

[anders-larsson]

How would you like us to proceed with this pull request?

Thanks and Best Regards,

In the Redhat documentation they say not to use nscd and sssd together for passwd, group, services and in 8 they say sssd is enabled by default. I don't see any solution other than nscd for hosts however. I believe nscd should work with redhat/centos 8 however only hosts should be enabled by default (at all really)

enable-cache hosts yes
enable-cache passwd no
enable-cache group no
enable-cache netgroup no
enable-cache services no

Hi @braddeicide,

Thank you for your contribution. It has been merged. I did squash your commits and change the commit message a bit though. I hope it is OK.
