Quang-Minh Nguyen requested to merge qmnguyen0711/handle-limit-error-in-workhorse into master

What does this MR do and why?

Return 429 and Retry-After header for Gitaly LimitError

When Gitaly returns a LimitError, it means Gitaly is at the capacity of a certain resource. It fails to serve that request. Returning 429 HTTP code and a Retry-After header is helpful. It's an indicator for clients to retry that request again.

Previously, clients received a 500 response code.
