Certain controllers (e.g. Doorkeeper::TokensController) don't expose the
method "request_format". This commit changes
Gitlab::Metrics::WebTransaction so we don't rely on this method, instead
using the underlying code this method uses.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/46412

GitHub uses a library called Licensee to identify a project's license
type. It shows this information in the status bar and via the API if it
can unambiguously identify the license.

This commit moves the reference to Creative Commons licensing from
the LICENSE file to the README, which allows Licensee to successfully
identify the license type of GitLab CE as MIT.

fix runner requirements

See merge request gitlab-org/gitlab-ce!18728

The method "content_type" on a controller does not always return the
correct content type. On the other hand, the method "request_format"
does _and_ immediately returns a Symbol (e.g. :json) instead of a
mime-type name (e.g. application/json). With these changes metrics
should again report their action names correctly.

Fixes https://gitlab.com/gitlab-com/infrastructure/issues/3499

It mentions that explicitly defining dependencies in sources is
preferred over defining such dependencies only in spec files.

Merge branch '46361-does-not-log-failed-sign-in-attempts-when-the-database-is-in-read-only-mode' into 'master'

Does not log failed sign-in attempts when the database is in read-only mode

Closes #46361

See merge request gitlab-org/gitlab-ce!18957

This commit has two migrations:

1. The first prunes duplicate rows in the project_features table and leaves
   the row with the highest ID.  Since the behavior was indeterministic before
   and depended on which row the database decided to use, this change at least
   makes the permissions consistent. For example, in some cases, the Wiki may
   have been disabled but enabled in another entry.

2. The second adds a non-null constraint on the project_features.project_id
   column.

Closes #37882

Fixes a significant part of gitlab-com/migration#408.

We found that we were overcounting Wikis because of these duplicates.
On GitLab.com, there are 56 rows with duplicate entries by project_id, and 16,661 rows with NULL project_id values.

Add index on ci_runners.runner_type
