About the usage of ipmi user management

[Lei YU]

With Richard and Tom's help, we are clear about the root cause of the issue:

* In `phosphor-ipmi-host_git.bb`, it installs the root into `ipmi` group
* When BMC is running in a clean environment, it just works
* If BMC is updated from an old version, the `/etc/group` is preserved during
   code update as it is in `/run/initramfs/whitelist`, so the new ipmi group
   does not work at all, the root only has `ssh` group.
* To make it work, we could do a factory reset, which makes the BMC to run
   from a clean environment.
   After factory reset, I confirm that the net ipmi works well, and
the root has below groups:

       root web redfish ipmi priv-admin

   Which probably means redfish may meet similar issue as well.
