This adds management/persistence.zeek to establish common configuration for log rotation and persistent variable state. Log-writing Zeek processes initially write locally in their working directory, and rotate into subdirectory "log-queue" of the spool. Since agent and controller have no logger, persistence.zeek puts in place compatible configurations for them. Storage folders for Broker-backed tables and clusterized stores default to subdirectories of the new Zeek-level state folder. When setting the ZEEK_MANAGEMENT_TESTING environment variable, persistent state is kept in the local directory, and log rotation remains disabled. This also tweaks @loads a bit in favor of simply loading frameworks/management, which is easier to keep track of.
