Some teams have a continuous build server that would mark certain manifest green and safe to sync to. Then team members could repo sync to that particular manifest file and make sure they always sync to a green build. But if she/he has some local changes and wants to rebase, currently it would be a manual process to find the correct version to rebase onto. This patch helps with that use case by automating the process to rebase onto the currently synced manifest version. Change-Id: I847c9eb6addf7f84fd3f5594fbf8c0bcc103f9a5
