Expose count of all sub-epics and issues in epic tree
A follow-up from this discussion: !22284 (comment 270633407)
In the epic-tree widget, we currently show only numbers of open/closed sub-epics and issues which user can see. The problem is that this gives inaccurate overall status about completeness of the epic. For this reason we should show counts of all open/closed sub-epics/issues there, even if it means we expose existence (only existence, no additional details) if a private/confidential sub-epic/issue.
Setting weight 2 because this is quite easy change and assigning to myself because I'm familiar with the original query I introduced in 12.6.
