This is a cluster backend implementation using a central XPUB/XSUB proxy that by default runs on the manager node. Logging is implemented leveraging PUSH/PULL sockets between logger and other nodes, rather than going through XPUB/XSUB. The test-all-policy-cluster baseline changed: Previously, Broker::peer() would be called from setup-connections.zeek, causing the IO loop to be alive. With the ZeroMQ backend, the IO loop is only alive when Cluster::init() is called, but that doesn't happen anymore.
