Create the specified remote directory during backup
This is idempotent, so there's no harm calling it if the directory
already exists.

Include Wiki attributes in Wiki page events webhook
The hook data we are sending is not 100% correct (we send details of the project, but should also send details of the "ProjectWiki" attributes like URLs and repositories relative to the wiki itself).
This is a follow up to #17506Fixes#17507

Remove project notification settings associated with deleted projects
On GitLab.com, there are 1560 project notification settings with no valid project all created on 2016-04-15 10:38:53 for some reason. This migration should purge
those entries.
b8f38437 should prevent this issue from occurring in the first place.

Add Application Setting to configure Container Registry token expire delay (default 5min)
This adds an option to configure Container Registry token expire delay. The default is set to 5mins (something that is also used by Docker Hub).
What is left:
* [x] Write test to check the expire_delay
Fixes: https://gitlab.com/gitlab-org/gitlab-ce/issues/17890
@stanhu I think that this should land in patch release of 8.8.

Make authentication service for Container Registry to be compatible with < Docker 1.11
This removes the usage of `offline_token` which is only present when using `Docker 1.11.x` instead we relay on `scope`. This should make it compatible with any client starting from 1.6 (I did test only 1.8 and up).
Right now we return 403 if unauthorized user doesn't have access to anything. In all other cases we return token, but with empty `access`, which simply disallow requested action.

Enable Style/NegatedIf Rubocop cop
Favor `unless` over `if` for negative conditions (or control flow ||).
```ruby
# bad
do_something if !some_condition
# bad
do_something if not some_condition
# good
do_something unless some_condition
# good
some_condition || do_something
```
