Fix import/export merge requests error

When MWBS is set and the MR exported/imported an error gets thrown. We should ignore this so it can succeed as the merge user may no longer exist in the target instance.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/24009 and https://gitlab.com/gitlab-com/support-forum/issues/1345

Accept environment variables from the `pre-receive` script

## Summary

1. Starting version 2.11, git changed the way the pre-receive flow works.
  - Previously, the new potential objects would be added to the main repo. If the pre-receive passes, the new objects stay in the repo but are linked up. If the pre-receive fails, the new objects stay orphaned in the repo, and are cleaned up during the next `git gc`.
  - In 2.11, the new potential objects are added to a temporary "alternate object directory", that git creates for this purpose. If the pre-receive passes, the objects from the alternate object directory are migrated to the main repo. If the pre-receive fails the alternate object directory is simply deleted.
2. In our workflow, the pre-recieve script (in `gitlab-shell`) calls the
   `/allowed` endpoint, which calls out directly to git to perform
   various checks. These direct calls to git do _not_ have the necessary
   environment variables set which allow access to the "alternate object
   directory" (explained above). Therefore these calls to git are not able to
   access any of the new potential objects to be added during this push.

3. We fix this by accepting the relevant environment variables
   (`GIT_ALTERNATE_OBJECT_DIRECTORIES`, `GIT_OBJECT_DIRECTORY`, and
   `GIT_QUARANTINE_PATH`) on the `/allowed` endpoint, and then include
   these environment variables while calling out to git.

4. This commit includes these environment variables while making the "force
   push" check.

* Also is not a good idea to use File.open without closing the file

Update NGINX configuration files to add websocket support

## What does this MR do?

Changes the bundled NGINX configuration files to support websockets introduced in https://gitlab.com/gitlab-org/gitlab-workhorse/merge_requests/83

These changes are also going into omnibus: https://gitlab.com/gitlab-org/omnibus-gitlab/merge_requests/1146

## Are there points in the code the reviewer needs to double check?

Best to wait until the omnibus MR is merged as the method may be changed.

## Why was this MR needed?

Without it, NGINX won't let websockets through to workhorse.
