This commit appends the README.md to state that yaml files should start
with `---` and end with `...`. This also addresses some linting
warnings that were not appearing during pre-commit on local system.
-> Changed specific pieces that are recommended to be changed in Ansible
2.7 and higher (such as using fail_msg and success_msg, not just msg for
assertions
-> Improved the getkeytab adhoc playbook for flexibility and delegations
against a IPA server, as well as forcing the choice of the user with
permissions that can perform the action rather than the default "admin"
user in FreeIPA as a security fix.
moved inv vars to group vars
moved roles to collections and fixed playbooks
added a prepare ansible host playbook to download needed roles and playbooks
modified public roles and collection paths to install inside our dir structure to keep them from global installation
