Description of problem: A user of the Satellite web UI cannot find detailed information about the changes made to a Content View between versions. This information would be useful when troubleshooting, also in confirming that the changes they intended are complete, and that the Content View is ready to be published. It would also help in instances where there are multiple Satellite administrators, as each could quickly determine what changes had been made between one CV version and another.

How reproducible: Always

Steps to Reproduce:
1. Open the Satellite web UI and navigate Content > Content Views.
2. Make a change to a Content View, and save it.
3. Publish the new version.
4. Navigate to the example Content View's "Versions" tab.

Actual results: There is no detail of change occurred to the Content View between the current version and the previous version(s).

Expected results: The table in the "Versions" tab would contain details of the changes made to the Content View between each version. Details such as: repositories added or removed, filter(s) added or removed, filter's start or end date changed.
