Create placeholder model in CE for Vulnerability

See merge request gitlab-org/gitlab!42147

This change adds new placeholder model for Vulnerability and moves
previously created model to EE::Vulnerability module.

This is a bit more acceptable: just under 2min, and 1175 examples.

This includes a bunch of optimizations (avoiding re-creating issues,
being very careful about resets) that means we can run over a range of
size 6 (2606 examples) in about 4min 30s.

We want the `new_item` to be a new, unplaced item.

We have made `move_sequence` a private method, so we need to call it
using send.
