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
