This patch cut a new release of the horizon for the stable/yoga branch.
The main purpose of this branch is to include below patches:
1. Do not assume keystone admin endpoint 3a65699602
2. Add SYSTEM_SCOPE_SERVICES setting that hides panels f5620931d6
Note: above two patches are important to have in the stable/yoga
branch otherwise few panel under Identity dashboard are broken and
System Scope menu is not hidden by default which can confuse the user
who don't want to use System Scope.
