Prevent cluster migration spec from interfering with later specs

See merge request gitlab-org/gitlab-ce!16255

When seeding the GDK with new projects, it's very common to reuse
the same repository names on disk. Previously, the validation would
fail and leave the projects in a half-broken state. We can skip
the validation to avoid causing odd errors.

Closes gitlab-org/gitlab-development-kit#310

This already existed in EE with a different timestamp, so rename for CE and make

Improve filtering issues by label performance

Closes #40500 and #37143

See merge request gitlab-org/gitlab-ce!16136

If a later spec tries to set a field that is added to any of these models by a
later migration than the GCP clusters migration, it will fail because the
model's columns are cached.

We should always refer to models in migration specs by either their class in the
migration, or the table directly, using the `table` helper.
