[Neutron] [train] Horizon port security group management fails

Hey Sean,

Thanks for the reply.

For reference, I have all the steps to reproduce along with the relevant
debug logs attached to this LP:
https://bugs.launchpad.net/neutron/+bug/1989627

But, to summarize. If I go to any random instance in Horizon as a member
user - not a admin. Then try to remove any Security Group at all from any
of the ports it fails with the policy violation (I attached a screenshot of
where I'm making that change in Horizon). But doing it with the same user
from the cli works fine. Since I'm editing individual interfaces there,
rather than the instance itself. I assumed these would all be API calls to
Neutron from Horizon rather than from Horizon to Nova.

I just run server list --all to demonstrate I was indeed using a member
user and not a admin since an admin would have seen VM's from all projects.

I agree with you in principle. It should be exactly the same whether it
comes from openstackclient or from Horizon. In fact, I was 98% positive I
would be able to demonstrate the wrong user was being used in this case.
But unfortunately, my efforts to reproduce it demonstrated that the two are
indeed handled differently.

I believe anyone should be able to reproduce it using the steps I outlined
on the LP.
