Previously imports would fail if a merge request note included a
suggestion with an
`ActiveRecord::HasManyThroughCantAssociateThroughHasOneOrManyReflection`
exception.

This was happening because suggestions were listed as a descendant of
merge requests, but this doesn't work because suggestions are directly
associated with notes, not merge requests, and that association is lost.
Rails also disallows creating intializing a has_many association through
a different object.

We fix this by making `suggestions` a child of `notes` within a merge
request. This doesn't fix previously broken exported project exports,
but new exports will work.

See merge request gitlab-org/gitlab-ce!31354

Splits auto-refreshing of MR widget into 2 requests:

- the one without caching

The idea is to gradually move all the fields to etag-cached endpoint

Backport EE changes to Members::BaseService

See merge request gitlab-org/gitlab-ce!31581

Resolve EE differences in the lib/ directory

See merge request gitlab-org/gitlab-ce!31582

This change was made in EE in MR
https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/14802, but this
was not backported to CE.

This spec used a different title for a spec in EE, while CE duplicated
the same title. This ensures that CE uses the EE version.

Add Gitaly and Rugged call timing in Sidekiq logs

See merge request gitlab-org/gitlab-ce!31651

Resolve "Misalignment of Avatar when forking project"

Closes #65204

See merge request gitlab-org/gitlab-ce!31436

- use .mx-auto for avatar
- remove parent div for group_icon

This will help identify Sidekiq jobs that invoke excessive number of
filesystem access.

The timing data is stored in `RequestStore`, but this is only active
within the middleware and is not directly accessible to the Sidekiq
logger. However, it is possible for the middleware to modify the job
hash to pass this data along to the logger.
