Description of problem:
System registration to the CDN fails with the GUI tools Anaconda and Cockpit fails with the message "You must specify an organization for new units" if attempted with an account that is part of more than one logical organization.

Version-Release number of selected component (if applicable): 8.x


How reproducible:


Steps to Reproduce:
1. Attempt to register any RHEL 8 system using Anaconda or Cockpit with an account that is part of more than one organization.
2. Observe that registration fails with "You must specify an organization for new units" and that neither tool gives you any opportunity to select an organization before attempting registration.


Actual results: registration fails with "You must specify an organization for new units".


Expected results: registration succeeds, OR registration dialog allows you to select an organization prior to attempt


Additional info:
This has been a known issue since at least September 2020 (See: https://access.redhat.com/discussions/5363891) From what I can tell at some point the CDN registration process began requiring an organization when registration is performed through a GUI and the account is a member of more than one organization.  While I can surmise the purpose of this change is to allow for correct subscription allocation by organization, the tools should have been updated to handle the scenario before the CDN was updated to reject registration requests without an "organization" value.

"subscription-manager register" run on the command line succeeds for the same user account without requiring the user to provide an organization, but this workaround has some considerable drawbacks.  Firstly it defeats the purpose of keeping subscriptions separated between organizations because it just seems to arbitrarily choose an organization. Secondly, the registration information is still not recognized by Cockpit when subscription-manager was used to entitle the system so anyone using Cockpit to verify subscription status will be misled into believing the system is not registered.

This request is to address the disconnect between the GUI registration tools (Anaconda and Cockpit) and the CDN behavior by adding dialog options to either select an organization prior to registration, or a "choose one for me" option which uses the same logic that "subscription-manager register" does.  I also strongly believe that the CDN behavior should be updated to stop rejecting registration requests without an "organization" value until this has been fixed in Anaconda and Cockpit.
