Enhance Redfish to allow IPMI users

[Joseph Reynolds]

I am working on a new feature so the BMC admin can use Redfish 
operations to allow or deny specific users to use the BMC's network IPMI 
interface.
The goal is to be able to configure the BMC out of the box with no users 
authorized to use the IPMI network service, and then as needed enable 
network IPMI and allow specific users to use that service.

The direction for this seems to be adding the IPMI enum to the 
ManagerAccount AccountTypes array.
https://redfishforum.com/thread/219/account-groups-property?page=1&scrollTo=1289

If we had this, the BMC admin could allow someuser to use IPMI like 
this: PATCH /redfish/v1/AccountService/Account/someuser with 
{AccountTypes: [...,IPMI,...]} and possibly also changing the password.

Would this work with OpenBMC phosphor user management?  The forum thread 
has additional considerations.  Will the IPMI maintainers please comment 
here or on the forum?
