Description of the problem, including code/CLI snippet

When using the CLI command: gitlab group-member all [...] the accepted parameters are incorrect. The all "endpoint" should operate just like the list, 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 the gitlab docs --id is not necessary and you should actually be able to search (probably something to add for the normal list as well.
