heat: fix key_uuid format

The .format() won't work, since it can't slice the uuid

We have to convert the uuid to string before we slice it.
I thought .format() would implicitly call __str__() before
applying width, but that is not the case.

'files/yardstick_key-{:.{width}}'.format(self.key_uuid, width=8))

We also need to define a constant short uuid lenght, we can't
hardcode the length to 8 everywhere.

Create a helper function to standardize the generation
of the short key uuid and use that helper function everywhere
