A user granted the "view_group" permission should be able to access groups. Not just on the group page, but in the groups drop-down on the namespace edit page. This is no longer working in 4.3, but was working as of 4.2.2 by my comparison tests.

Reproduction steps:

• Create a new user
• In the django shell, grant the user the view_groups permission
• Do not grant the user superuser access
• Attempt to add this user to the owner field of a namespace via the groups (Cloud version)
