Remove Unnecessary System Upgrades from Installer

[lisaSW]

Summary

During installation, both our Ansible installer and the RITA pre-installation process perform a full update/upgrade of target operating systems. This can cause breaking changes to existing servers and cause unintended side effects.

Additionally, the RITA installer contains a post-installation process that involves mandatory rebooting of all remote installation targets due to mass system upgrades.

Requirements

• Perform only required package management activities (remove all full distribution package upgrades)
• Properly install Ansible from pipx instead of via package manager, no longer install Ansible package repository
• Remove any packages installed for troubleshooting purposes
• Improve error handling and messaging
• Remove post-installation Ansible playbook
