Allow external related issues
Description
Currently it's not possible to add a related issue to an issue if it exists outside of GitLab. When I try adding a generic URL in the field, I get the following message:
We can't find an issue that matches what you are looking for.
This would be useful for projects with issues that need to track upstream project issues and other related issues where in both cases, the referred-to projects are hosted outside of GitLab.
Issue URLs could be in Launchpad, GitHub, etc. as not all projects are hosted in GitLab (yet).
Proposal
Allow generic URLs in the Related issues field.
