When any two storages are configured identically it was previously
impossible to move projects from one to the other. This is because
before trying to move the repository we check if the storages are
identical to prevent dataloss. Instead of bailing out with an exception,
now we simply update the database. This allows admins to update all
projects before fixing the configuration error.

Wait up to 60 seconds instead of 30 seconds till PIDs should exist.

Replace bootstrap event strings with constants

See merge request gitlab-org/gitlab!52777

This replaces the usage of the following bootstrap event names with
constants defined in ~/lib/utils/constants.js.

| Event Name           | Constant           |
| -------------------- | ------------------ |
| `bv::hide:tooltip`   | `BV_HIDE_TOOLTIP`  |
| `bv::dropdown::show` | `BV_DROPDOWN_SHOW` |
| `bv::dropdown::hide` | `BV_DROPDOWN_HIDE` |

Set `projects.has_external_wiki` to `DEFAULT false` and `NOT NULL`

See merge request gitlab-org/gitlab!50916

This change contains migrations for `projects.has_external_wiki` to
become a `NOT NULL` column that defaults to `FALSE`.

This is possible after the PG Trigger added in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/49916 that always
maintains `projects.has_external_wiki` as a boolean and never a `NULL`.

It includes a data migration to set all historical `NULL` columns to be
either `TRUE` or `FALSE`.

The data migration also fixes the historical bad data for
`has_external_wiki`:

The current subgroup migration strategy works iteratively, which means
that each level of a group tree is imported before moving to the next
level.

This becomes a problem when the target group is within the source group,
which creates a _infinity_ loop of import.

>> Example:

Given a group tree like:

- Group A
  - Group B
  - Group C
    - Group X
    - Group Y

If one decide to import the Group A into Group B, a recursion will
happen, making the import stop only when the depth limit is achieved or
some other database constraint, like the size of a group path.

- Group A
  - Group B
    - Group A
      - Group B
        - Group A
          - Group B
            - Group A
              - Group B
                - ...
              - Group C
                - Group X
                - Group Y
          - Group C
            - Group X
            - Group Y
      - Group C
        - Group X
        - Group Y
  - Group C
    - Group X
    - Group Y

To fix that, destination namespaces cannot be a descendant of the source
group.
