Document Rugged settings for Puma
We need to document that Rugged needs special configuration settings when running Puma:
- In the Puma documentation: https://docs.gitlab.com/omnibus/settings/puma.html
- Reference in the NFS documentation: https://docs.gitlab.com/ee/administration/high_availability/nfs.html
We should recommend running with a threadcount of 1 if you still need to use Rugged.
Note: I don't think we can say it is deprecated, because people on NFS will not be able to move off NFS until Gitaly HA is ready, which may be after 13.0.
