Documentation: Katello Required Ports on Foreman Server is missing port 5646/TCP for Smart Proxy installation

We opened the firewall ports according to the 3.17 Katello docs, 80, 443, 5647 and 9090. After installing a smart proxy we see the following errors in the smart proxy /v/l/m:
SERVER (info) [C14868] Connection to foreman.local.lan:5646 failed: proton:io No route to host - disconnected foreman.local.lan:5646

After opening port 5646/tcp on the foreman server, the errors went away and we have this:
Connection Opened: dir=out host=foreman.local.lan:5646 vhost= encrypted=TLSv1/SSLv3 auth=ANONYMOUS user=(null) container_id=foreman.local.lan props={:product="qpid-dispatch-router", :version="1.14.0", :"qd.conn-id"=3}

Expected outcome:
The documentation should list port 5646/tcp in addition to 5647/tcp for Smart Proxy communication.

Foreman and Proxy versions:
Foreman 2.2.1, Katello 3.17

Foreman and Proxy plugin versions:

Distribution and version:
CentOS 7.9

Other relevant data:
Current doc extract:
## Required Ports

The following ports need to be open to external connections:

* 80 TCP - HTTP, used for provisioning purposes
* 443 TCP - HTTPS, used for web access and api communication
* 5647 TCP - qdrouterd - used for client and Smart Proxy actions
* 9090 TCP - HTTPS - used for communication with the Smart Proxy

Thanks for bringing this to our attention @rbremer. We will work on fixing this gap in that part of the documentation. The smart proxy diagram does lay this out but is not consistent across all points where we mention ports.

Thank you!

I’ve opened a PR to address updating both the server and proxy port requirements when using Katello.
