Suggestion for a new command:
Add a set user for a O365 Group that allows for promoting a member to owner, or demoting owner to member.

Current implementation is done through Teams and the same rework approach should be taken as #847 and #846 (add new command, and keep old alias for backwards compatibility)

command: o365group user set -u| --userName <userName> -i| --teamId [teamId]| --[groupId] <groupId> --role <role>

• userName: the UPN of the user to add
• teamId: id of the team
• groupId: id of the Group
• role: Member or Owner. Default Member

Please assign to me :-)
