Managing SMD groups is a little weird using the ochami smd group sub-command.
If I have existing groups and I want to update the memberships I currently have to do the following:

- if group doesn't exist: POST
- if group exists
   - get existing list of members
   - get new list of members
   - do a symmetrical diff
   - DELETE then POST if there is a difference

I don't see a way to update the group membership with going through the above steps.

ochami smd group member set <group> <members> returns:

unsuccessful HTTP status: HTTP/2.0 405 Method Not Allowed: {\"type\":\"about:blank\",\"title\":\"Method Not Allowed\",\"detail\":\"allow GET\",\"status\":405}\n"

ochami smd group update -d@payload.yaml -f yaml just returns the help menu. It doesn't tell me why though.

What I would like to see is a way to update group membership with a single command line call that:

• Deletes members if they are in the group but not in the new payload
• Adds members if they are not in the group but in the new payload
• Leaves members if they are in the existing group and the new payload
