Why:

* The create service would return as successful when the record is
  invalid if the record already preexisted.

This change addresses the need by:

* Only return as successful if feedback is persisted AND valid

Respect member access level for group shares

Closes #56

See merge request gitlab-org/security/gitlab!192

Previously, we only considered the access level set for the
GroupGroupLink when calculated ProjectAuthorization or
Group#max_member_access_for_user for the shared group. We need to
consider access level in the shared with group as well, which might be
lower than the one set for GroupGroupLink.

Validates secrets provided to FileUploader in order to prevent
directory traversal attacks. We generate 32-byte hexadecimal secrets
now and 10-byte hexadecimal secrets in the past, so these are the only
two valid formats permitted.

Also adds a test that proves the exploit works without the change, and
a test that proves the change resolves the exploit.

* Validate the grafana URL setting to ensure it is a valid URL and does
not contain javascript.
* Add a rel='noopener noreferrer' attribute to the link on the frontend
so that when the link is opened in a new tab, it will not be able to
control the tab from which it was opened.
* Use the system_hook_validator for grafana_url since it is an admin
setting.
* Add migration to remove any javascript URLs from
application_settings.grafana_url.
* Add a blocked_message option to addressable_url_validator. The option
allows a custom error message to be added if the URL is blocked.
* Add a parse_url method to Gitlab::Util which returns an
Addressable::URI object.
* Add changelog entry.
