CE backport for gitlab-org/gitlab-ee!15433 (Expose DesignType#notes_count in GraphQL)

See merge request gitlab-org/gitlab-ce!32037

Notes call `#after_note_created` and `#after_note_destroyed` on their
noteable in callbacks, so the noteable can perform tasks particular to
them, like cache expiry.

This is in preparation of the EE-specific class
`DesignManagement::Design` clearing its `user_notes_count` cache when
its note are created or destroyed.

Refactoring Rspec behaviour testing of a counter caching service into a
shared example.

Resolve "MR resolve conflicts file headers bad positioning on scroll"

Closes #60141

See merge request gitlab-org/gitlab-ce!31991

The file title sometimes overflows its container, which has the same
border-radius. By always rounding the file title, the overflow never
happens, so the corners always look correct.

Everywhere else there are file diffs, there is a top border to complete
the full border around the file.

CE-backport: Move create cluster Vue apps to create_cluster directory.

See merge request gitlab-org/gitlab-ce!32220

This commit creates a create_cluster directory to collect
all Vue applications related to creating kubernetes applications
using gitlab.

It also moves the gke_cluster_dropdowns collection of apps to
the create_cluster directory. gke_cluster_dropdowns contains
dropdown components used to select configuration options to
create a Kubernetes cluster in Google Cloud.

Update DB migrations style guide: prefer atomic migrations when possible

See merge request gitlab-org/gitlab-ce!31915

Currently, the DB migrations guide says that "you must" use non-blocking
operations (such as CREATE INDEX CONCURRENTLY), always.

But this does not make sense in cases of empty tables and leads to
splitting the work to multiple non-atomic
(with disable_ddl_transaction!) DB migrations.

To follow KISS principle, to have fewer DB migrations steps,
to have them atomic when it's possible and simplify deployment
and troubleshooting, the following exceptions were added
to the doc:

- index creation,
- index dropping,
- defining an FK,
- adding a column with DEFAULT,
