Seed tablesample strategy

Closes #58791

See merge request gitlab-org/gitlab-ce!25966

The change in
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/24199 caused
requests coming from a load balancer to arrive as 127.0.0.1 instead of
the actual IP.

`Rack::Request#ip` behaves slightly differently different than
`ActionDispatch::Request#remote_ip`: the former will return the first
X-Forwarded-For IP if all of the IPs are trusted proxies, while the
second one filters out all proxies and falls back to REMOTE_ADDR, which
is 127.0.0.1.

For now, we can revert back to using `Rack::Request` because these
middlewares don't manipulate parameters. The actual fix problem involves
fixing Rails: https://github.com/rails/rails/issues/28436.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/58573

This produces stable approximate counts among invocations unless the
table changed.

Resolve CE to EE differences in the lib/api directory

scheduled we want to prevent unexpected consequences.

Remove fake repository_path response - resolved issue# 50386

Closes #50386

See merge request gitlab-org/gitlab-ce!25942

The repository_path is no longer needed since
https://gitlab.com/gitlab-org/gitlab-shell/merge_requests/231, which closes
https://gitlab.com/gitlab-org/gitlab-shell/issues/135.

Authenticate the internal API using a header

See merge request gitlab-org/gitlab-ce!25924

When an empty project is loaded in the UI, there are 15 separate Gitaly
FindDefaultBranch calls to determine the root_ref. Previously, it was
not cached even within the request. This change caches it within the
request so only a single FindDefaultBranch RPC is needed.
