Install StorageGRID host services

Summary

The default package manager for RHEL 8 or later has changed from yum to DNF, however, rhel_install_from_repo.yml file which is contained in storagegrid installer (e.g.StorageGRID-Webscale-11.6.0-RPM-20220210.0232.8d56cfe.tgz) is still using yum as package manager.

This caused installation fails as below

TASK [storagegrid : Install StorageGRID from YUM repository] **** fatal: [Non-Primary-Admin-Node]: FAILED! => {"changed": false, "msg": "The Python 2 yum module is needed for this module. If you require Python 3 support use the dnf Ansible module instead."}

details error logs: python2.install.error.txt python3.install.error.txt

It has been confirmed that edited the rhel_install_from_repo.yml file as below can workaround the error. But customer requested Netapp officially verified documents. So please help to confirm and update the doc ASAP. Thanks!

The yml file's format becomes strange so attached the capture for clarification:
