Task:

Given an existing Pod named web-pod running in the namespace database.

1. Edit the existing Role bound to the Pod's ServiceAccount test-sa to only allow performing get operations, only on resources of type Pods.

2. Create a new Role named test-role-2 in the namespace database, which only allows performing update operations, only on resources of type statuefulsets.

3. Create a new RoleBinding named test-role-2-bind binding the newly created Role to the Pod's ServiceAccount.

Note: Don't delete the existing RoleBinding.
