Fix file locking spec and quarantine locks directory spec

See merge request gitlab-org/gitlab!19380

Test was quarantined due to a bug: https://gitlab.com/gitlab-org/gitlab/issues/35254
Changed hardcoded "Adminstrator" in expectation to a username

In https://gitlab.com/gitlab-org/gitlab/merge_requests/16926 we added
gRPC timeouts for calls that did not previously have timeouts to prevent
Sidekiq queries from getting stuck. In addition, we also made long
timeouts 55 seconds for non-Sidekiq requests, but this meant Rake tasks
also fell into this bucket. Rake backup tasks with large repositories
would fail because the CreateBundle RPC would time out after 55 seconds.

To avoid this trap, we flip the logic of long_timeout: instead of
checking for Sidekiq (or other background jobs), we only lower the
timeout to 55 seconds if we're servicing a Web request in Puma or
Unicorn.

Closes https://gitlab.com/gitlab-org/gitlab/issues/22398

Add `edit` endpoint for Release page

There are several steps to this process:

* GitLab assumes the role provided by the user and stores
  a set of temporary credentials on the provider record. By default
  these credentials are valid for one hour.

* A CloudFormation stack is created, based on the template in
  vendor/aws/cloudformation/eks_cluster.yaml. This triggers creation
  of all resources required for an EKS cluster.

* GitLab polls the status of the stack until all resources are ready,
  which takes somewhere between 10 and 15 minutes in most cases.

* When the cluster is ready, GitLab stores the cluster details and
  fetches another set of temporary credentials, this time to allow
  connecting to the cluster via Kubeclient. These credentials
  are valid for one minute.

* GitLab configures the worker nodes so that they are able to
  authenticate to the cluster, and creates a service account for
  itself for future operations.

* Finally, all details and credentials that are no longer required
  are removed.

Updated to kubectl v1.13.12 and helm v2.15.1

Option to prevent LDAP sign in

Closes #15626

See merge request gitlab-org/gitlab!18749

When LDAP is used for group sync and SAML for authentication,
it can be preferable to disable LDAP sign in for security.

Issues like https://gitlab.com/gitlab-org/gitlab/issues/34749 show, that
the worker is vulnerable for exceptions happening during model update in
DB. What's worse is that exceptios happening on this level, are failing
the whole execution of StuckCiJobsWorker, which unnoticed ends with
thousands of stale pending/running/scheduled jobs waiting in the queue.

This commit re-uses the fix added with
https://gitlab.com/gitlab-org/gitlab/merge_requests/19150 to properly
handle and log such exceptions and drop the jobs regardless of them.

Geo - Rename Geo::FileRegistry model to Geo::UploadRegistry

Closes #10067

Add real world config to overcommit example

See merge request gitlab-org/gitlab!19322

- it would be nice to have a working file in here as an
  example file.
- this brings us one step closer to hopefully utilizing
  overcommit in CI and/or at least on each dev's machine
- next step would be for gdk install to copy it over,
  drop the extension and install it
- or drop the .example on this file and make it the default,
  and users will merely have to run a `overcommit -i` after
  installing overcommit gem
