Description of the problem, including code/CLI snippet

When using the CLI command:gitlab group-member all [...] the accepted parameters are incorrect. Theall "endpoint" should operate just like thelist, allowing paging, etc. instead, it seems to have some other specific commands that aren't necessary.

Expected Behavior

Being able to use commands such as,

• gitlab group-member all --group-id 212 --page 2
• gitlab group-member all --group-id 212 --per-page 2 --page 10
• etc.

Actual Behavior

gitlab group-member all only accepts:

 -h, --help           show this help message and exit  --group-id GROUP_ID  --sudo SUDO  --id ID

as specified in thegitlab docs--id is not necessary and you should actuallybe able to search (probably something to add for the normallist as well.
