Method to reproduce:

1. Create test user with _member_ role.
2. Create test flavor
3. Booted instance using test user with test flavor.
4. Go to the flavor in horizon and click on Edit Flavor.  Don’t change anything and hit save.
5. test user with _member_ role will no longer be able to query data with cli.

1. Users should have view access to flavors that are previously deleted owned by tenant by default - I am unsure how to fix this via policy.json after a few tests will need help.
2. When modifying access and setting extra_specs in horizon flavor uuid should not change to match behavior from cli.
3. When no changes are made after hitting Edit Flavor, the flavor should not be deleted and recreated with new uuid.
4. This should also possibly apply to renaming of flavors as well.
