Handle Stored XSS for Grafana URL in settings

See merge request gitlab/gitlabhq!3481

- Extend Gitlab::UrlBlocker to allow relative urls (require_absolute
  setting).  The new `require_absolute` setting defaults to true,
  which is the existing behavior.

- Extend AddressableUrlValidator to accept `require_abosolute` and
  default to the existing behavior

- Add validation for ApplicationSetting#grafana_url to validate that
  the URL does not contain XSS but can be a valid relative or absolute
  url.

- In the case of existing stored URLs, validate the stored URL does
  not contain XSS. If the stored URL contains stored XSS or is an
  otherwise invalid URL, return the default database column value.

- Add tests for Gitlab::UrlBlocker to test require_absolute setting

- Add tests for AddressableUrlValidator

- Add tests for ApplicationSetting#grafana_url

Filter out search results based on permissions to avoid bugs leaking data

See merge request gitlab/gitlabhq!3494

This will be used later for search filtering.

This is to be more consistent as there is already a :read_note policy in
NotePolicy. To keep other behaviour the same we've introduced a
Note#noteable_ability_name that is used anywhere this was expected.

Previously, when the wiki page format was anything other than `markdown`
or `asciidoc` the formatted content would be returned though a Gitaly
call. Gitaly in turn would delegate formatting to the gitlab-gollum-lib
gem, which in turn would delegate that to various gems (like RDoc for
`rdoc`) and then apply some very liberal sanitization.

It was too liberal!

This change brings our wiki content formatting in line with how we
format other markdown at GitLab, so we have a SSOT for sanitization.

This makes it so we mask Sentry's auth token. This mask only occurs in
the UI.
