[OpenStackSDK] Create yoga branch for client and non-client libs

This creates the stable/yoga branch for all client and non-client
libraries now that we are past the lib freeze on February 24th.

If the team wants to wait for a specific patch to make it to the
library, someone from the team can -1 the patch to have it held, or
update that patch with a different commit SHA.

Patches with no response will be merged by Friday, March 4th.
