Fix broken link in HA docs

Whoops! Fix broken link in docs from gitlab-org/gitlab-ce!3579

See merge request !3890

Updated HA docs and open to public

Closes https://dev.gitlab.org/gitlab/organization/issues/624

We still need to go through the old gitlab.com/standard/high-availability and move relevant docs over, plus do some docs on DRBD. However, I think this is a good volume for the first pass. Can we get this out there and then iterate?

Move cherry-pick feature specs to proper directory

Cherry pick feature specs were located in `spec/feature/project` directory while we have `spec/feature/projects`.

Later location is consistent with our namespaces (we have `Projects::` namespace, not `Project::`).
