Eric Fried 683ffb097c refactor: RequestGroup.is_empty() and .strip_zeros()
This makes an is_empty() method on RequestGroup which answers whether
the group has any resources, traits, or aggregates; and a strip_zeros()
method which removes any resources whose amount is zero.

These are used to refactor ResourceRequest.strip_zeros().
_clean_empties() becomes not worth keeping in its own method, so it's
rolled into ResourceRequest.strip_zeros(), its only consumer. At the
same time, the worthless (at least now that we're py3-only)
ResourceRequest.resource_groups() generator is removed and inlined in
the couple of places it was used.

In addition to simply making the code more cohesive, a later patch will
make use of RequestGroup.is_empty() to forbid no-op groups coming from
ports, accelerators, etc.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.
