[keystone] Create zed branch for client and non-client libs

This creates the stable/zed branch for all client and non-client
libraries now that we are past the lib freeze on September 1st.

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, September 9th.
