Temporarily disable parts of heal port allocation test

Due to bug 1894825 the nova-next job fails on master as the allocation
key cannot be deleted from the binding:profile of a neutron port. This
patch temporarily disable this test step while the bug is being fixed
and a new neutronlib is released with the fix.
