Get ports directly instead of via loop
In order to get a list of available ports, the current implementation
of the form code in `project/instances/attach_interface` loops through
the available networks in the project and requests a list of ports for
each via the Neutron API. This implementation is O(N) in time with a
large prefactor (the time for a Neutron API call) where N is the
number of networks.
Instead of calling the Neutron API for each network this change uses
one call to the Neutron API to get the list of ports on all networks
and filters this list via a list comprehension. While this
implementation is still O(N) the prefactor is significantly smaller.
Includes some unit test fixes to workaround the fact that patch
6ac31e0 is not backported beyond Y.
