Make requirements voting again, update .zuul.yaml

Change  Ibc77ea864503e63f73be0f1c41e07bfe8ea3dcae needed a non-voting
requirements change for merging, since this is in, we can make
requirements voting again. For this, just remove it.

Remove voting from the neutron-tempest-plugin-designate job since
non-voting jobs should not run in gate.

Remove name from project-stanza, this is not needed anymore.

Rename designate grenade job to follow
