Upstream Katello PR: https://github.com/Katello/katello/pull/6310

Verified.
Version Tested: Satellite-6.3 Snap 11

Composite content views now show if there are newer versions available of the content views that comprise the composite.

I performed the following steps to verify this issue:

1. Created 2 content views and published them,

2. Created 1 composite content view comprised of the other two.

3. Set one to 'latest' and the other to the latest version. and published the composite view.

4. published new versions of the original content views

5. looked on the composite view's content view list. The "latest" was already at the newest version, and the other listed that a newer version was available, and listed newest version.

Screenshot attached.
