Update API for new Content View Options (needs_publish)

[tmichett]

SUMMARY

Now that Foreman (Satellite) has the ability to analyze content views and support a "needs published" feature, it would be nice to support this for Ansible. Currently, whenever Ansible playbooks are used around content views, it will create/publish new CVs when this isn't needed. This makes the playbook non-idempotent and causes a lot of extra CVs.

ISSUE TYPE

• Implement the needs_publish for the content views similar to the flags that will be available in hammer.
