zuul: Move legacy jobs to project

Implement part of step one of the zuulv3 migration guide: move the
purely nova projects to the nova repo [1]. This does not migrate any
jobs used in other projects nor does it convert what is migrated to use
the new 'devstack' or 'devstack-tempest' base jobs. Both of these steps
should be done separately.

What's migrated:

- experimental:
  - legacy-tempest-dsvm-nova-lvm (renamed to nova-lvm)

What's dropped:

- experimental:
  - legacy-tempest-dsvm-nova-lxc (no one's using this)
  - legacy-tempest-dsvm-nova-wsgi-full (WSGI is the default since Pike)

What's still to be migrated, here or to other projects:

- check:
  - legacy-grenade-dsvm-neutron-multinode
  - legacy-grenade-dsvm-neutron-multinode-live-migration
  - legacy-tempest-dsvm-cells
  - legacy-tempest-dsvm-full-devstack-plugin-ceph
  - legacy-tempest-dsvm-neutron-linuxbridge
  - legacy-tempest-dsvm-neutron-multinode-full
  - legacy-tempest-dsvm-neutron-nova-next-full
  - legacy-tempest-dsvm-multinode-live-migration
  - ironic-tempest-dsvm-ipa-wholedisk-bios-agent_ipmitool-tinyipa
  - legacy-tempest-dsvm-neutron-full
  - legacy-grenade-dsvm-neutron
- gate:
  - legacy-tempest-dsvm-cells
  - legacy-tempest-dsvm-multinode-live-migration
  - legacy-tempest-dsvm-neutron-full
