Description of problem:

Despite following all the steps from "Chapter 3. Configuring your Satellite infrastructure to communicate with Insights" of https://access.redhat.com/documentation/en-us/red_hat_insights/2022/html-single/using_cloud_connector_to_remediate_issues_across_your_red_hat_satellite_infrastructure/index#configuring-your-satellite-infrastructure-to-communicate-with-insights ,

The "Configure Cloud Connector" job will fail to setup cloud-connector if remote_execution_ssh_user is set to a non-root user.

It will only be successful in one-shot if the remote_execution_ssh_user is set to root but that is not widely accepted.

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

Any version of Satellite 6
( Tested on 6.9 , 6.10 , 6.11, 6.12 )

How reproducible:

Always

Steps to Reproduce:

1. Install a fresh Satellite 6.11 or 6.12

2. Confirm that it is properly registered with Red Hat portal

3. Change the value of "remote_execution_ssh_user" to "rexuser"

1. hammer settings set --name remote_execution_ssh_user --value rexuser

4. Execute the steps from "3.1. Uploading your host inventory from Satellite to Insights for RHEL" , specifically the installer command.

1. satellite-installer --foreman-proxy-plugin-remote-execution-ssh-install-key true

And then do a manual "Inventory Upload" from Satellite UI by clicking on Restart button for the required organization

5. Go to Configure -> Inventory Upload page and click on "Configure Cloud Connector" button

Actual results:

Step 4 is successful but it shares the foreman-proxy ssh key to only the root user of satellite ( which is expected as per the code in /usr/share/foreman-installer/modules/foreman_proxy/manifests/plugin/remote_execution/ssh.pp )

At Step 5, the cloud connector job execution will immediately fail

Simply because

A) rexuser does not exists

B) Even if we will create it on satellite, It will not have the foreman-proxy SSH public key copied

So the end-user needs to end-up using the steps from https://access.redhat.com/solutions/5196351

Expected results:

If this is an expected behavior then that should be clearly documented in https://access.redhat.com/documentation/en-us/red_hat_insights/2022/html-single/using_cloud_connector_to_remediate_issues_across_your_red_hat_satellite_infrastructure/index#proc-uploading-your-host-inventory-from-satellite-to-insights_remediating-satellite

Or, The command "--foreman-proxy-plugin-remote-execution-ssh-install-key" flag should copy the SSH keys to the remote_execution_ssh_user i.e. rexuser in this case.
