update_all and insert_all are pretty efficient and can easily handle a
few thousand records.

We can remove loggable_arguments given that the arguments are numeric.

Using 'an idempotent workers' shared example to test the idempotent of
the workers.

We don't need to pluck the set of ids into memory. We can pass the
ActiveRecord::Relation and use sub-queries.

This change makes the workers idempotent as it doesn't raise any error
if the integration is no longer found.

This updates all inherited integrations using the same approach of
batching and Sidekiq queue that we use when bulk create integrations for
project and group integrations.

Including the id column in the partial index improves performance.

This is an important change in the architecture to propagate
integrations. We can now propagate instance-level integrations and
templates using batching and Sidekiq queues.

The problem before is the performance of the worst-case scenario, where
if there are no matching records and the anti-join. With the new
approach, each job in the new queues handles a batch of projects/groups;
rather than having a single job for all of them.

This is what we do right now in the complex case of propagating an
instance-level integration:
- Update inherited integrations,
- Create integration for all projects without integration.
- Create integration for all groups without integration.

BEFORE:

                 Save integration
                        ↓
            ┌┬───────────────────────┬┐
            │| Propagate integration |│
            └┴───────────────────────┴┘
                        ↓
           Update inherited integrations
  Create integration for all projects without integration
  Create integration for all groups without integration

AFTER:

                 Save integration
                        ↓
            ┌┬───────────────────────┬┐
            │| Propagate integration |│
            └┴───────────────────────┴┘
               ↓                   ↓
  ┌┬─────────────────────┬┐ ┌┬───────────────────────┬┐
  │| Propagate to groups |│ │| Propagate to projects |│
  └┴─────────────────────┴┘ └┴───────────────────────┴┘
            Update inherited integrations

Closes #250654

See merge request gitlab-org/gitlab!43321

There are two changes required:

* Add an Accept: application/vnd.git-lfs+json header to batch requests
* Support the verify action

Without the former, GitHub (but not GitLab) responds with a 406 HTTP
response to the batch request. With it, GitHub responds with a spec
indicating that `verify` should be used.
