feat: Like v1, have roles at the group-level (v1 are organizations) #7633
Description
Version: v0.23.5+ef2411e
A prospect/enterprise would like a group-level template admin role, so a user in that role can see and administer all templates in that group.
Coder v2 has either a site-wide template admin or a template-level admin, who actually cannot create templates only administer them.
As a result, this enterprise will have to set up multiple deployments of Coder with separate license files.
Another existing customer comes to mind who has a lot of organizations in v1, with various roles to add images, only use images, add registries, etc.
