Added endpoints:
- `scheme` as a whole new endpoint
- `update_scheme_derived_roles_of_channel_member` in `channels`
- `set_channel_scheme` in `channels`
- `convert_channel` in `channels`
- `update_scheme_derived_roles_of_team_member` in `teams`
- `delete_team_icon` in `teams`
- `set_team_scheme` in `teams`
- `get_stats` in `users`

Fixes:
- `create_user` in `users` was missing the query parameters
