Port the grenade multinode job to Zuul v3

It implements the same behavior of the old one.

It is worth noting that the existing job the MULTI_KEYSTONE does not
produce any effect because this change hasn't been merged yet:
- https://review.opendev.org/399472
and when that merges, the following devstack-gate changes should be
applied directly to this new job definition instead:
- https://review.opendev.org/394895

Both changes are out of scope for this porting.
