Manage users allowed to authenticate.

This endpoint allows you to create, read, update, and delete configuration
for Okta groups that are allowed to authenticate, and associate policies to
them.

Deleting a group will not revoke auth for prior authenticated users in that
group. To do this, do a revoke on "login/<username>" for
the usernames you want revoked.
