[WIP] CE 8-5-stable to EE 8-5-stable-ee

Unresolved conflict:

• app/views/projects/milestones/show.html.haml

The problem is that the milestone/show view has changed in CE:

but in EE there was mention of the "total issues weight" in the "Issues" tab:

I don't know how to resolve this conflict since it requires a UI change... I think we could add (total weight: XX) before the YY% complete part.

Note: I don't think we'll actually merge this MR, I just need to know how to resolve this conflict.

Here's what it looks locally with my suggestion:

@rymai LGTM. We'll need to make sure the same change happens during the master CE-to-EE merge for consistency. cc @vsizov

@rspeicher Right, here is the part of code that has been modified (the EE-specific code is separated with blank lines above and below):

    %span.milestone-stat
      %strong= @milestone.open_items_count
      open and
      %strong= @milestone.closed_items_count
      closed

      - total_weight = @milestone.issues.sum(:weight)
      - unless total_weight.zero?
        = surround '(', ')' do
          total weight:
          %strong= total_weight

    %span.milestone-stat
      %strong== #{@milestone.percent_complete}%
      complete

Status changed to closed
