Dynamically rename Tempest resource post-update

Renamed the Tempest resource name after updates using the
"cifmw_test_operator_tempest_name" parameter.
This change enables the test operator role to run multiple
times consecutively without requiring resource cleanup,
improving test isolation and efficiency.
