Fix not being able to edit Billing members

[ccremer]

Summary

v0.24 of control-api has been released, which creates automatically the admin cluster role for billing entities when created. This removes the need (and assumption) that the portal should be managing both ClusterRole and ClusterRoleBinding. Now, only the ClusterRoleBinding is required to be edited.

Also fixes the redirect after saving the members -> goes back to BE details instead of Zones.

I added @bastjan as a reviewer for this. From a priority perspective, this is not urgent. The cause, triggering this, is unlikely to happen within the next days(/weeks).

There will still be cases where a sudoer needs to create those roles from the portal GUI. We still have customers in the Odoo that might request access but can't see their BEs since they are not setup correctly.

We might add some reconciling logic for the roles but would prefer to correct the rules here until we have smth like this.

See for correct rules:

@corvus-ch @bastjan I don't quite understand what the holdup is for this fix.
Right now (also in Prod), when users create a billing address and then try to edit members (billingentities/be-xxxx/members), they get presented with an error and the glitchtip reporter dialog. This PR primarily addresses this issue so the reporter doesn't show up anymore.

As i said: there is no reconciliation and no guarantee that the admin role is created if an existing, wrongly setup BE is enabled/fixed. We still need the admin role creation for VSHN support team members.

I'd strongly prefer to update the role creation code with the rules i linked.

Ok, leaving this for now. Let me know if you prefer to disable this view temporarily, so that users can't click/visit the BE members list view.

I might misunderstand the issue.

Why not just create the roles as defined here? #535 (comment)

[corvus-ch]

As far as I understand, this issue does not surface when users create their BillingEntity on their own. Only when they get created in the ERP. So, this is not an issue to expect within the next days. Instead of wasting time with some workarounds (which we might have to remove again later) in the frontend, I would prefer to fix this for good in the API.

As far as I have just tested, this issue does in fact surface for user-created BillingEntities as well.

I just created a billingentity through the portal (using a new account created through social login), and subsequently when I click on "edit members", the issue described above pops up (error message + glitchtip popup). So it is not as uncommon as we initially thought.
