Description of problem:

While investigating https://bugzilla.redhat.com/show_bug.cgi?id=2122461 and after installing the `foreman-redis` package, trying to configure `redis` as the rails cache store with:

`satellite-installer --foreman-rails-cache-store type:redis`

the installer will fail because it'll try to configure port 8479 instead of 6379.

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

Satellite 6.13 Snap 8

How reproducible:

Always.

Steps to Reproduce:
1. Install `foreman-redis` package from brew
2. Run: `satellite-installer --foreman-rails-cache-store type:redis`
3.

Actual results:
