JIRA Integration: Fix API URL with trailing slash

Add AWS cluster provider

Add individual inherited member lookup API

See merge request gitlab-org/gitlab!17744

Adds the endpoints

    /(groups|projects)/:id/members/all/:user_id

for finding individual members, including inherited membership,
complementing the existing endpoints

    /(groups|projects)/:id/members
    /(groups|projects)/:id/members/all
    /(groups|projects)/:id/members/:user_id

which list direct members, list all members (including inherited), and
find individual direct members, respectively.

Consider the scenario:

1. The snippet visibility level is set to internal
2. A user attempts to create a private snippet

Previously this would always fail because `default_value_for` would
overwrite the private visibility setting, no matter what
visibility_level was. This was happening because `default_value_for` was
confused by the default value of 0 specified by the database schema.

`default_value_for` attempts to assign the default value in the block by
checking whether the attribute has changed. The problem is that since
the default value by the database was 0, and the user requested 0, this
appeared as though no changes were made. As a result,
`default_value_for` would always overwrite the user's preference.

To fix this, we remove the use of `default_value_for` and only set the
visibility level to the default application setting when no preference
has been given at creation time.

This is similar to the fix in
https://gitlab.com/gitlab-org/gitlab-foss/merge_requests/29578.

Fix showing diff when it has legacy diff notes

See merge request gitlab-org/gitlab!18510

Do not try to unfold `LegacyDiffNote`s as they don't support
`position` even though they're in the same `notes` table as
`DiffNote`s.

This is done by using `Gitlab::Diff::PositionCollection` which
will be responsible for filtering the positions.
