Dropping the OemOpenBMCPerformService privilege and custom 
OemOpenBMCServiceAgent role in favor of a more general design.

DISCUSSION:

The design above will intersect with its counterpart 
operation-to-privilege design - in that they both specify privileges.  
We should sketch out that design before proceeding with this one. Next 
piece is operation-to-privilege customization design because it affects 
this design.

Anton reviewed his doc.  We discussed having the D-bus broker use ACLs.

Key to get reviews: create something each maintainer can test.

Need to cover all D-Bus users with ACL before we can throw the secure 
switch (rough number of services to be changed 
<https://gerrit.openbmc-project.xyz/c/openbmc/meta-phosphor/+/37844>for 
a based set of targets runnable under qemu).
