Rename zuul v3 job

Rename job to follow naming conventions for a shared global namespace:
https://docs.openstack.org/infra/manual/drivers.html#consistent-naming-for-jobs-with-zuul-v3

Also, remove name from project stanza, it's not needed for in-tree zuul
files anymore.

Keep old name to allow renaming, a followup will remove it.
