RedHawk is not fully recognized as a RedHat-based distribution

Description of Issue

Please add yumpkg as provider for RedHawk
Because this is a Red Hat based distribution, I installed CentOS salt-minion.

Setup

(Please provide relevant configs and/or SLS files (Be sure to remove sensitive info).)
If I try to use the following state:
sudo_pkg:
pkg.installed:
- pkgs:
- sudo

I get this:

      ID: sudo_pkg
Function: pkg.installed
  Result: False
 Comment: State 'pkg.installed' was not found in SLS 'linux.generic.sudoers.redhawk'
          Reason: 'pkg' __virtual__ returned False

When I put the following in the / etc / salt / minion, it works as it should.
providers:
pkg: yumpkg

Steps to Reproduce Issue

(Include debug logs if possible and relevant.)

Start by reproducing the pkg.installed failure on RedHawk and compare it with the working minion providers configuration using yumpkg. Trace the platform detection and package-provider selection involved in the pkg entry point. Done means pkg.installed is available on RedHawk without the manual provider override, with coverage for this distribution behavior.
