bundle2: allow lazily acquiring the lock In the external pushrebase extension, it is valuable to be able to do some work without taking the lock (like running expensive hooks). This enables significantly higher commit throughput. This patch adds an option to lazily acquire the lock. It means that all bundle2 part handlers that require writing to the repo must first call op.gettransction(), when in this mode.
