Disable request buffering for new SSH endpoints

What does this merge request do and why?

Contributes to gitlab#466160 (closed)

Problem

While testing the new implementation of SSH endpoints for git related actions. I noticed a problem reproducible in my local environment.

The request from GitLab-Shell to Workhorse was hanging. After in investigation I discovered the root cause of this problem.

In our NGINX configuration we use request buffering. After adding the new endpoint to the list of exceptions, then problem was resolved.

Solution

Add new endpoints to the list of exceptions for nginx configuration.

How to set up and validate locally

New endpoints are not ready yet. But I think the change is straightforward.
