Removed smoke tags from all -api job tests

Most of the smoke tests now in the Neutron tree were inherited from Tempest
and are in the process of being reconciled back. Since [1], Neutron tests
can be run via a Tempest plugin, therefore there is a chance that these
are picked up unwillingly by some CI systems (like the one of Puppet
sub-project).

We should purge the tags for now, complete the de-fork and consider which
ones are worth the tag again.
