Thomas Woerner ba4a360520 New idview management module. 
There is a new idview management module placed in the plugins folder:

    plugins/modules/ipaidview.py

The idview module allows to ensure presence and absence of idviews and
idview host members.

Here is the documentation for the module:

    README-idview.md

New example playbooks have been added:

    playbooks/idview/idview-absent.yml
    playbooks/idview/idview-host-applied.yml
    playbooks/idview/idview-host-unapplied.yml
    playbooks/idview/idview-present.yml

New tests for the module can be found at:

    tests/idview/test_idview.yml
    tests/idview/test_idview_client_context.yml
