In I147bf4d95e6d86ff1f967a8ce37260730f21d236 we added a new argument for the rebuild_instance() RPC method. Unfortunately, we missed to that it needs to be optional for older versions. Adding a default none value for it so rolling upgrades would work. Change-Id: I59c5e56b00114fea5ec19fa63ec73f032dc3bd5c Closes-Bug: #1902925
