Merge branch '17298-wiki-xss' into 'master'
Forbid scripting for wiki files
Wiki files (not pages - files in the repo) are just sent to the browser
with whatever content-type the mime_types gem assigns to them based on
their extension. As this is from the same domain as the GitLab
application, this is an XSS vulnerability.
Set a CSP forbidding all sources for scripting, CSS, XHR, etc. on these
files.
Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/17298.
See merge request !1969
