Devstack cannot be created for yoga due to the git branch name changes

[Dominik Danelski]

Since some repositories like nova changed name of the yoga branch (stable/yoga to unmaintained/yoga), stack.sh for this OpenStack version fails, because it cannot fetch the branch using the old name.

See the last 49 lines of stack.sh output:

Discussed today, tldr: it may take a while to setup yoga in unmaintained/ namespace:

As I've noticed, Devstack saw a change of the branch name from stable/yoga to unmaintained/yoga. Still, stack.sh fails for the same reason as stated originally: it still tries to fetch stable/yoga at some point.
