New host management module
There is a new user management module placed in the plugins folder: plugins/modules/ipauser.py The host module allows to add, remove and disable hosts. The host module is as compatible as possible to the Ansible upstream ipa_host` module, but addtionally offers to disable hosts. Here is the documentation for the module: README-host.md New example playbooks have been added: playbooks/host/add-host.yml playbooks/host/delete-host.yml playbooks/host/disable-host.yml
