Initialize _keys in __init__() in FakeFlavorResource

Tang Chen · Tang Chen · commit c57fc41c33df · 2016-02-23T00:14:56.000+08:00
_keys is defined as a class attribute in FakeFlavorResource. So when
we call set_keys() to update it, it changes. And this change may bring
trouble to the other tests afterward.

So define and initialize it in __init__() as an object attribute.
