TestAttachInterfaces fails on neutron w/parallelism

[Salvatore Orlando]

Failure instance: http://logs.openstack.org/85/64185/1/experimental/check-tempest-dsvm-neutron-isolated-parallel/94ca5ac/console.html.gz#_2013-12-27_13_37_15_639

This failure is the 3rd most frequent with parallel testing (after the error on port quota check and the timeout due to ssh protocol banner error)

It seems the problem might lie in the fact that the operation, when neutron is enabled, does not complete in the expected time (which seems to be 5 seconds for this test).

Possible approaches:
- increase timeout
- enable multiple neutron api workers (might have side effects as pointed out by other contributors)
- address the issue in the nova/neutron interface

    AttachInterfacesTest: use build_timeout on iterface deletion

    Currently the test uses 5 seconds timeout.
    This patch changes it to use configured build_timeout
    in interface deletion check

Seems to be fixed for neutron jobs
