zuul: clean up some legacy jobs

Replace legacy-tempest-dsvm-lvm-multibackend with its native version,
cinder-tempest-lvm-multibackend.

Remove legacy-tempest-dsvm-neutron-dvr-multinode-full, which was defined
as an experimental job in neutron and removed during the ussuri lifecycle.
See https://review.opendev.org/#/c/693630/
It seems neutron-tempest-dvr-ha-multinode-full should cover its use case.
