Foreman Maintain

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1733287

Description of problem:

Procedures::Packages::Install should be after epel repo check

If you have epel repo enabled and run foreman-maintain its possible it will fail when it tries to get packages for the speed test.

Version-Release number of selected component (if applicable):

[root@dell-r330-12 ~]# rpm -q rubygem-foreman_maintain
rubygem-foreman_maintain-0.4.5-1.el7sat.noarch

How reproducible:
depends on packages versions for libpmem at the time

Steps to Reproduce:
1. enable epel repo (yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm)
2. foreman-maintain upgrade run --target-version 6.6.z --whitelist="disk-performance,repositories-validate,repositories-setup"
3.

Actual results:

~]# foreman-maintain upgrade run --target-version 6.6.z
