The DVCS connector uses the application token over GitLab API calls to
perform some of its required webhook configuration.

For this to succeed, the wider api scope needs to be selected instead
of the limited read_api scope.

The integration cannot function successfully if the read-only scope
is provided instead.

In MR https://gitlab.com/gitlab-org/gitlab/-/merge_requests/63669 we
introduced a new data format for storing merge request diff commit
authors and committers. As part of this work we made changes to the
import/export code to support this new format, and added a set of
migrations to migrate existing data to this new format. At this time we
supported reading and writing of data in both the old and new format,
allowing us to gradually migrate data over to the new format.

In https://gitlab.com/gitlab-org/gitlab/-/merge_requests/72219 we
ensured all migrations are done, stopped using the old data format, and
removed the columns storing this data.

Unfortunately, this chain of events uncovered a bug in our import/export
logic. Consider the following timeline of events:

1. You export project "Cooking Recipes" from a GitLab instance running a
   version earlier than 14.1 (e.g. 14.0).
2. The instance you intend to import this project into is running 14.1
   or newer. Existing data has been fully migrated already.
3. You import the project into this new instance.

At this point, the imported data is using the old format, not the
format. This is because we forgot to take into account users importing
exports using GitLab 14.0 or older, instead only covering exports
generated using GitLab 14.1 or newer. Because the background migrations
finished, or the data imported would fall in a "bucket" (= a chunk or
rows to migrate) that had already been migrated, the data would never be
updated to the new format.

In this commit we resolve this problem in two steps. First, we change
the import/export logic to support importing data in both the old and
new format. Exports still use the new format. In addition, we include a
background migration that processes all projects created using a GitLab
import/export since the first mentioned merge request was introduced.
For each such project we scan over the merge request diff commits and
fix any that are missing the commit author or committer details.

For small self-hosted instances this process is unlikely to take more
than a few minutes. On GitLab.com however we expect this process to take
a few days, as we have to process around 200 000 projects imported since
July. This means we'll likely need additional manual intervention
similar to the manual work needed for
https://gitlab.com/gitlab-org/gitlab/-/issues/334394.

See https://gitlab.com/gitlab-org/gitlab/-/issues/344080 for additional
details.
