Rework of repository maintenance and backups

Browse Source 
It will now attempt to wait until there are no other active transactions before starting, to avoid deadlocks. A timeout for this process is specified - generally 60 seconds - so that callers can give up or retry if something is holding a transaction open for too long. Right now we will give up in all places except for bootstrap creation, where it will keep retrying until successful.
