- Also stop polling if we get a bad response from the server.

**Why timeout 0?**
Sometimes we want to poll without timing out.

**Why an object argument?**
It's helpful to pass these extra properties by name.
`simplePoll(cb, { timeout: 0 })` is nicer than
`simplePoll(cb, undefined, 0);`

GitLab, Anonymous!".

This brings back some of the changes in
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20176/diffs.

We discovered another N+1 that hits Gitaly `TreeEntry` via the
`RelativeLinkFilter`:
https://gitlab.com/gitlab-org/gitlab-ce/issues/58657. When a blob is
loaded with many relative links, `TreeEntry` is called for each link to
scan the URI type.

There are multiple paths that hit Gitaly `TreeEntry`, and
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/25706 did not
cover all cases. This commit covers another common use case.

For users using Gitaly on top of NFS, accessing the Git data directly
via Rugged may be faster than going through than Gitaly. This merge
request introduces the feature flag `rugged_commit_tree_entry` to
activate the Rugged method.
