ipatests: add integration test for "Read radius servers" perm

Add a new integration test for the following scenario:
- create a user with the "User Administrator" role
- as this user, create a user with a --radius=<radius_proxy_server>

This scenario was previously failing because ipa user-add --radius
requires read access to the radius server entries, and there was no
permission granting this access.
