What

The confluent rbac role list test was improperly formatted. This test was setup in a way to call multiple namespaces containing different roles in a single test. Over time, this test degraded and was setup to call the same namespace multiple times, resulting in the test showing a duplicated list of roles. This initial testing strategy came from a concept that customers could query our list endpoint for different role namespaces. The two issues with this are:

1. We have migrated from this strategy, and now the default call to our RBAC list API returns all production roles across all namespaces
2. The CLI did not have the ability to query on a per-namespace basis anyways, making this functionality pointless.

This test should not have a comprehensive list of all production roles, as that wouldn't really be testing anything of value and would require constant updates. Instead, this test has been modified to only return a few of our roles in a single namespace, which allows us to ensure the formatting of the output is correct, which is all we can gain from this test anyways.

Blast Radius

There is no end-user blast radius associated with this change, as it only touches an integration test and no public feature.
