Add flag to not install epel-repo on Centos/Rhel

Description

In RHEL enterprise installations we should not install the `epel-repository` package as
1. It's highly likely that they have an internal mirror containing the packages we would otherwise fetch from the epel repository
2. If it's an air gapped installation, yum won't be able to fetch the repo package list, failing the recipe execution and a manual intervention is required.
