In https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20654 this job
was marked as allowing failures, but this allows developers to ignore
the results that Danger produces. Since it's not clear why the job was
allowed to fail, and since it's somewhat counter productive, we no
longer allow it to fail.

Before a 404 would be rendered only after a request to Gitaly would
return with an InvalidArgument error. Now we check that the ref have a
valid format before sending it to Gitaly. In both cases, a 404 is
returned to the user, but this change prevents Gitaly from generating
error noise in production.

Closes https://gitlab.com/gitlab-org/gitaly/issues/1425

This enables #allow_user_defined_namespace? to work so that the form for

That shows that we cannot create a new group cluster
