https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/24624 extracted
the X-Forwarded-For address directly, but this didn't consider the case
where multiple proxies are in the chain. To fix this, we use the Rails
implementation to filter trusted proxies, as documented by Grape:

EE Allow Gitaly N+1 in MR CreationsController

Closes #9917

See merge request gitlab-org/gitlab-ee!9671

When a user clicked on another page in the pipeline page, the following
would happen:

1. PipelinesService.getPipelines() would be called to fetch the new page
2. In the success handler, Poll.restart() would be called
3. This would invoke Poll.makeRequest(), which would fire off a new
request.

To fix this, we introduce a enable(), which will:

1. Update the request data accordingly
2. Clear the old timeout if necessary and start a new timer

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/58095
