New Features ============
* The zuul delete-state command may be used to delete all of the ephemeral state stored by Zuul in ZooKeeper. Normally Zuul is able to detect and correct errors on its own, but in case it is unable to, this may prove a useful utility for manual recovery.
* The new commands zuul copy-keys and zuul delete-keys may be useful when renaming projects in order to move the keys from the old to the new project names without service interruption.
* Add new statsd gauge metrics of current open node requests exported as zuul.nodepool.tenant.<tenant>.current_requests. This metric tracks the currently open node requests per tenant. It drills down the overall zuul.nodepool.current_requests metric.
Upgrade Notes =============
* Zuul no longer reads or writes project private key files from the scheduler’s filesystem. In order to load existing keys into ZooKeeper, run version 4.6.0 of the scheduler at least once, if you haven’t already.
* A new command zuul export-keys has been added to export the encrypted keys from ZooKeeper onto the filesystem for backup. Likewise, zuul import-keys will load a previously-exported backup into ZooKeeper. It is recommended that you use these commands in system backup scripts.
