Add mirror access control

Motivation:

Sometimes you need to restrict access to specific repositories
without allowing mirroring for all repositories. These repositories may
contain sensitive information or code that is only available to a
select group of members.

Modifications:

- Add `MirrorAccessController` that can allow or disallow access to
  the remote repositories for mirroring.
  - It is used to check a scheduled mirroring task or a task triggered
    by UI is allowed to access.
  - `MirrorListener.onCreate()` and `MirrorListener.onUpdate()` events
    are newly added. The events could be used as an extension point to
    detect a new remote URL pattern and integrate external systems
    such as a workflow or a email notification.
- Add CRUD REST API for administrators
  - GET `/api/v1/mirror/access` to retrieve all mirror access
    controls.
  - POST `/api/v1/mirror/access` to create a mirror access
    controls.
  - and so on...
- In addition to the REST API, a mirror access control can be added
  with `MirrorAccessController.allow(...)` API which is exposed by
  `PluginContext.mirrorAccessController()`.
- Add `CrudRepository` abstraction to easily create and update a
  collection of entities in a directory.
  - This API would be useful especially when we implement UI-based CRUD
    operations.
- Add mirror access control UI for administrators
  - CRUD are supported.

Result:

- Administrators can restrict access to remote repositories when mirroring.
- You can receive notifications when a new mirror is created or an
  existing mirror is updated through `MirrorListener`.
