Disable resource_finder_cache in controllers
Heat caching somehow messes our tests so we disable it before the tests start. For instance, if we do: 1. create example-net with NET_ID1 2. create VNFD1 with example-net 3. delete VNFD1 4. delete NET_ID1 5. create example-net with NET_ID2 6. create VNFD2 with example-net heat has NET_ID1 cached as the id of example-net and tries to use that instead of NET_ID2 to create VNFD2. This off course leads to a crash since NET_ID1 does not exist anymore. In the future we should investigate further why heat cache does not play well for us (probably bc of tacker).
