Merge branch '18028-respect-fork-project' into 'security'

Enforce the fork_project permission in Projects::CreateService

Projects::ForkService delegates to this service almost entirely, but needed one small change so it would propagate create errors correctly.

CreateService#execute needs significant refactoring; it is now right at the complexity limit set by Rubocop. I avoided doing so in this commit to keep the diff as small as possible.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/18028
