Drop neutron-tempest-multinode-full job from Tempest
Drop neutron-tempest-multinode-full job from Tempest

This patchset drops neutron-tempest-multinode-full job from
Tempest since Tempest now has an in-tree Zuul v3 version called
tempest-multinode-full (which is voting, while this legacy
job being removed is non-voting). tempest-multinode-full
replaces neutron-tempest-multinode-full [0].

This is to cut down on extraneous resource consumption
that is being dedicated to an obsolete job.
