* patch nltk egg so that the default data location is (buildout_directory)/parts/nltk-data without explicitly specifing by NLTK_DATA environment variable.
* download collection can be overridden like 'collection = aaa bbb ccc'.

    Use master instead.

    nexedi/slapos@000d0e5a (comment 4716)

So lamp-edge -> master

@rafael says:

    development stuff from marco, it was probably removed or not even
    included.

    In theory you can use master instead.

Shacache now uses CDN based URL for download.


  Update configuration to use CDN based domains for download date from CDN. 

See merge request !56

- GitLab Software + patches ported to latest stable GitLab 8.5.1
  (including fix for raw downloading to work in browser for private
repositories);
- Sync-with-upstream procedure streamlined (now only 1 branch for
  tracking upstream configuration files);
- Base software upgraded: Ruby, Redis, Nginx, Git;
- misc fixes.

    $ git diff 8.4.4+ce.0-0-g1680742..8.5.1+ce.0-1-ge732b39 --  \
        files/gitlab-cookbooks/gitlab/templates/default/sv-sidekiq-run.erb

shows nothing.

I manually reviewed

    $ git diff 8.4.2+ce.0-3-g68d5ee8..8.5.1+ce.0-1-ge732b39 \
        files/gitlab-config-template/gitlab.rb.template \
        files/gitlab-cookbooks/gitlab/attributes/default.rb

in omnibus-gitlab, and module proxy_set_header change, which we already
addressed in previous patch in Nginx config, there are no more changes
for us.

    - relative URL support: comment out - we do not need it - gitlab is
      always located at /.

    - Nginx-http: restore our version for proxy_set_header - upstream
      turned to allowing users to configure this, see e.g.

        https://gitlab.com/gitlab-org/omnibus-gitlab/commit/e13d5e42
        https://gitlab.com/gitlab-org/omnibus-gitlab/commit/a450585e

      but doing this way creates more complexity for gitlab SR, so I've
      restored our version which essentially does the same as default in
      omnibus-gitlab, and if we'll need to tune it - we can do directly in
      Nginx config.

      In other words slapos version does not allow users to tune nginx
      headers as instance parameter.

This does only pure merge. We will slaposify / adjust config and
corresponding md5sum in the following patches.

/cc @kazuhiko, @jerome

As it is said in 97dcf455 (gitlab: Establish proper 1 branch for
tracking upstream configs) we are switching to a model where we track
upstream configureation files on only one branch.

This merge does not change files on master - because we already have all
current upstream changes in - just establish a proper structure for future
updates.

Update GitLab software to

    - gitlab-ce 8.5.1 + NXD patches

      https://lab.nexedi.com/kirr/gitlab-ce/commits/8-5-nxd

    - gitlab-shell to 2.6.10 + 1 patch to remove unneeded hooks.old in *.git

      https://gitlab.com/gitlab-org/gitlab-shell/merge_requests/40

    - gitlab-workhorse 0.6.4 + NXD patches.

      https://lab.nexedi.com/kirr/gitlab-workhorse/commits/y/blobraw-4
      https://gitlab.com/gitlab-org/gitlab-workhorse/merge_requests/17

      ( download speedup patches got improved, and now also properly
        proxy _gitlab_session cookie to auth backend, so raw files for
        private repositories now open in browser ok )

This only updates software and begins SR update to 8.5 - for now gitlab
instance becomes non-working -- we'll pull in configuration files
updates and fixups in the following patches.

P.S. we also pin-up rubygems version, used to build gems, along the way.

GitLab uses git executable by full path as defined in gitlab.yml, but
not all places in code use it, e.g. here git is used just from $PATH

    https://gitlab.com/gitlab-org/gitlab_git/blob/2f0d3c1a/lib/gitlab_git/repository.rb#L259

So make sure to include our git into bundler-4gitlab PATH.
