Allow Users To Specify Packages by Configuration

[ewascent]

First, thanks. This is a solid module.

I am making an extension wrapper for this module. One area I am having to override is the install.pp. There are two things I would like to see addressed.

We prefer to install well versioned packages . This module has the packages hard coded in install.pp, without version information. I would rather the install class take variables. We can then pass in versioned packages.

The difference in "yum speak" would be
yum install samba-winbind-clients-4.7.1-6.el7.x86_64
instead of
yum install samba-winbind-clients.

We also want to install some krb packages as part of this module. We can add our own install.pp. Or you could allow packages to be passed into the install class as an array parameter.
