Keystone's configuration should have no bearing on the catalog
for nova's port. Nova's port is "static" data from the templated
catalog perspective.
The 'compute_port' option has been marked as deprecated and
slated for removal in the L release. The default/sample
templated catalog files do not rely on this option any
longer.
