Add tolerations and nodeSelector to test-operator-controller-manager

In previous PR [1], tolerations and nodeSelector parameters were added
to the test_operator role in order to configure tempest and tobiko pods.
This new PR adds the option to apply those parameters to the
test-operator-controller-manager pod as well.
