Description of problem:

While we can list the value of a Rule ID of a Content View filter via Hammer CLI, there is no way to list multiple values of it if we change the value of the same rule via Hammer CLI/Satellite WebUI, as at a given instance, the Rule ID can only have one value.

Version-Release number of selected component (if applicable):
Sat 6.15

How reproducible:
100%

Steps to Reproduce:
1. Create a Content View Filter.

2. Add an RPM rule.

3. Check the value of the Rule via Hammer.

~~~~

1. hammer content-view filter rule info --id <Rule ID> --content-view-id <CV ID> --content-view-filter-id <Filter ID>

~~~~

4. Change the RPM rule value via WebUI.

5. Check the value of the Rule via Hammer again.

~~~~

1. hammer content-view filter rule info --id <Rule ID> --content-view-id <CV ID> --content-view-filter-id <Filter ID>

~~~~

Actual results:
The command lists the updated value of the RPM Rule.

Expected results:

The command should list both values assigned to the RPM Rule.
