- Move UploadsTransfer to ProjectTransfer and inherit from this to UploadsTransfer and PagesTransfer

This sends a project_update hook when a repo is updated.  This does not include
renaming or transferring a project.  Those are covered by project_rename and
project_transfer.  This will get called, however, when the visibility is
changed.

Flushing the events cache worked by updating a recent number of rows in
the "events" table. This has the result that on PostgreSQL a lot of dead
tuples are produced on a regular basis. This in turn means that
PostgreSQL will spend considerable amounts of time vacuuming this table.
This in turn can lead to an increase of database load.

For GitLab.com we measured the impact of not using events caching and
found no measurable increase in response timings. Meanwhile not flushing
the events cache lead to the "events" table having no more dead tuples
as now rows are only inserted into this table.

As a result of this we are hereby removing events caching as it does not
appear to help and only increases database load.

If the GitHub project repository has wiki, we should not create
the default wiki. Otherwise the GitHub importer will fail because
the wiki repository already exist.

This bug was introduced here
https://gitlab.com/gitlab-org/gitlab-ce/commit/892dea67717c0efbd6a28f763
9f34535ec0a8747

Projects::ForkService delegates to this service almost entirely, but needed
one small change so it would propagate create errors correctly.

CreateService#execute needs significant refactoring; it is now right at the
complexity limit set by Rubocop. I avoided doing so in this commit to keep the
diff as small as possible.

Several tests depend on the insecure behaviour of ForkService, so fi them up at
the same time.

This moves tracking of the pushes since the last Git GC from PostgreSQL
to Redis. This reduces the number of writes on the "projects" table.
This in turn reduces the vacuuming overhead.

The lease used for incrementing the counter has been removed. This lease
was mostly put in place to prevent high database load but this isn't
needed anymore due to the counter now being stored in Redis.

Fixes gitlab-org/gitlab-ce#22125

Other improvements:
- Ensure slash commands autocomplete doesn't break when noteable_type is not given
