GitLab 11.2 limited the time-to-live (TTL) of unauthenticated sessions
via https://gitlab.com/gitlab-org/gitlab/merge_requests/6586 using
`before_action` in `ApplicationController`. However, this broke OAuth2
logins, which set the `current_user` **after** a login is successful, so
we moved it to an `after_action` in
https://gitlab.com/gitlab-org/gitlab-foss/merge_requests/21144. However,
`after_action` isn't called if a exception is raised in the request
cycle. Thus, in some situations, TTLs weren't always being set to a
short value.

This commit adds the TTL limiting to the Devise Failure App, which is
run anytime the user is redirected to the sign-in page.

Add project option for deleting source branch

Closes #18283

See merge request gitlab-org/gitlab!18408

Feature branches should be deleted after being merged into a stable
branch like master. This is not universally true, and accidentally
deleting a branch cause frustration and confusion for users.

The change:
- adds a Project Setting to control if 'Delete source branch' option is
enabled or disabled for new merge requests
- the Project Setting is on for new and existing projects

The previous default behaviour can be restored by toggling the new
setting.

Historically, the behaviour was changed to delete the source branch as
part of the merge widget refactor and then reverted 3 months later.

- Behaviour reverted fd72b4ed

This verifies the changed indexer behaviour from
https://gitlab.com/gitlab-org/gitlab-elasticsearch-indexer/merge_requests/44

We're also renaming the blob-related code to use `path` rather than
`filename`, to be consistent with the `Path` field in the ES index,
and the intention of this code (which deals with full paths, rather
than just filenames).

This also removes the `Elasticsearch::Git::LiteBlob` class, which isn't
used anymore and a leftover from the Ruby indexer which was removed in
https://gitlab.com/gitlab-org/gitlab/merge_requests/15641
